I'm a 35 year A.S.E certified Technician and no disrespect to the less experienced Tech in the video however his advice is TOTALLY false for this Exhaust system.Tuning is needed when installing totally new complete exaust system but muffler delete doesn't require tuning and it sounds absolutely amazing with the 5 inch Carven exhaust tips... I myself own the 2021 Widebody Scatpack 392 with mid muffler delete and Carven 5inch Chrome Tips and FYI a mid muffler delete is COMPLETELY harmless to the performance of this car weather at top end, Mid range, or Iow speed performance... Dodge electronic system is very sophisticated and the Engineering of the vehicle is designed to alert the driver if at any throttle position that power has been compromised... The PCM will trigger the " SERVICE ENGINE SOON" light to the driver whenever any factory settings has been altered. If you noticed whenever a muffler delete is performed that there's no requirements to reprogram the PCM as a result because simply no factory settings has been compromised... Dude needs some more training on Automotive electrical systems before taking shots at folks about what and how they choose to mod their vehicles...IJS

All I learned from this video is where not to take my car for exhaust work..

Presented by shops that want to sell a whole exhaust system.

Cool story bro, now cut my pipes.

I don't need this kinda negativity in my life 🤣

Me. dammm thats crazy.... Mechanic. You still wanna cut them Me.yep

I bet the customer will be like "Sir please hurry up and cut my pipe is getting late". Lol

Back pressure is a myth. Exhaust scavenging is what you want. Engineering explained covered this awhile ago. I've proved this on the dyno as well. You will NOT lose torque if you cut out your muffler, resos, put free flowing piping, etc. It may move somewhere in the rpm, but it is not lost, nor does it do any harm. If there are no sensors, you don't need a tune.

"He been a mechanic for as long as I was alive"... The guy proceeds to point at a Resonator and calls it a Muffler xD

He is wrong. First, the rear "mufflers" aren't mufflers they are resonators, they change the tone so you're not getting drone where the mufflers in the middle reduce the volume. Also, backpressure comments are just completely incorrect. He might be a decent mechanic but he doesn't understand the way exhaust works.

Is he jealous he doesnt have a scat? Man he seemed like he was gettin pissed.

I’d delete this video bro their are more people telling you he wrong then people agreeing 😂😂😂

You don’t lose back pressure from a muffler delete lol the X pipe brings the back pressure, go to another shop Nd cut your mufflers cause seems like he won’t do it

My dads been a mechanic for 40 years, he says this is extra and he’s tryna sell you it all 😂

Tech: This is why you don't cut your pipes. Me: Uh huh, that's crazy. Tech: Get a catback exhaust for... Me: Bruh, lower my car and give me my keys

Dude came for a mid muffler delete and got finessed into buying a thousand dollar exhaust system instead by the tech lol.

me: Damnnn bro that crazzzzyyy mechanic: So yea and this does- me: BRUH IF U DONT CUT MY SH SO I CAN GO ON WITH MY DAY

My scat feels exactly the same bud. Raced another with stock exhaust and we were neck and neck to 140 when we let off.

With all due respect, this guy simply doesn't know what he's talking about. The whole "backpressure" argument is complete nonsense. Opening up your exhaust doesn't cost you in performance. Deleting the resonators and adding Super 10's increased my RT's torque and gave it a great throaty bite. Performance didn't suffer in the least. I'd guess he's telling gullible people this nonsense trying to sell them expensive catback systems.

Oh hell no, even Americans are talking about that " back pressure " bullshit. No SIR mid muffler delete won't effect anything, meanwhile CATs delete yea u need to tune ur car to get the benefits.

So the same thing can be said about the wickerbill you have installed...you drilled holes into a perfectly installed factory spoiler for something that has 0 performance value

The loss of a little back pressure isn't going to make or break whether or not you lose that race.

Who's charging 200 for muffler delete I get it done for 75

Don't cut your mufflers because I have an 8k exhaust system to sell you.😀

Great explanation about how an engine works. However, if u ever saw the inside of these mid mufflers, you’d know they don’t create any additional back pressure. They are wide open on the inside. Maybe this 30 yr mechanic should know what the mid muffler is before he gives his “expert” opinion on it.

Mid Muffler Delete got nothing to do with performance. It's for sound more aggressive

He preaching 🔥lol, he been waiting for this moment🤣

Absolute wives tale.

Except everyone does this and has been fine...for 50 years...in practically every performance oriented car. Dumb video. >> If the advice is to get a tune so the car knows what is going on, then yeah sure. That is common sense.

At the same time i hear other mechanics call back pressure a myth

We Just Got Our Scat Today March 27.... 2 Lit family been rocking with knockout on IG & KZfaq for a while now.... U was one of few that really motivated us 💯..... Preciate you Knock ✊🏾 .....

Hey 360 what should I do for hellcat man I want quad tip I wanna take vaccum tips off and put quad tips 5inch...but should I leave pipe line stock?

This guy seems to have good intentions but it makes no difference. Won’t hurt the car. I’ve cut the mufflers off all 7 V8 trucks I’ve had and both of my camaros and had no issues. Many will say back pressure is a myth.

Look to me not everyone gots 1,200 or more for exhaust. Thats rent or mortgage payment or money you saving for vacation or hard times. We all don't need rolex and Invicta watch or G-shock just fine. If you got da bread drop it on exhaust. Do what u want to your car just do dont up badge it lol.

I love my exhaust on my F30(not sure if it's factory or aftermarket because I waited for the depreciation before I purchased it). She's quiet when I want her to be and in sport+ when I get on it, she opens up beautifully. She's not too loud, just right to turn all the heads. In a tunnel...OMG it sounds amazing at WOT.

I got a serious question. Im looking at a durango RT and i think they mid muffler deleted. What would it take or about how much to reverse it back to factory??

Your engine is an air pump. You want air out, as quickly as you can get it in. Mid muffler delete is for sound, not performance.

If deleting your Mids, would hurt performance or damage your vehicle. Dodge wouldve already addressed this issue. By putting out some kind of statement saying “Deleting mid mufflers will cause loss in performance and possibly damage your vehicle and void your warranty”. And there are thousands of muffler shops across America doing this. And not one mechanic has ever told me. “ Hey pal, I gotta warn you I wouldn’t do this.” The Mids on these cars are basically a straight through design anyways. Cutting the Mids off does not affect performance, only sound. Your X-pipe should provide enough “back pressure”. But if you’re one of those OCD guys that wants it clean, drop 1200 on a Borla or Corsa for a nice clean look and that “distinctive brand sound”. But if you just want some extra sound cutting the Mids off for 100-200 dollars, won’t hurt you Bro. It seems like he didn’t want to do it, and was trying to sell you an aftermarket system that he had overstocked in the back. If you ever decide to sell the car or trade your car in, keep the factory mufflers and have them reinstalled. My Son has a 2020 Charger Scatpack WIdebody Smoke Show, with Mid delete. I personally myself, like the way the stock mufflers sound over the delete. I enjoy your content Bro, keep it up!👍

Hey man I have a question if I replace my existing factory exhaust with a borla or corsa exhaust system will that void my warranty and is it worth installing it l? I just want a deeper sound and better performance by the way I have a 2021 Dodge Charger Rt with resonator deletes currently.

What is a good resonater to put in if I already have muffler deleted? I want more sound without cab drone. Please help me out.

The "car exhaust needs back pressure" myth completely goes against how exhaust scavenging works to evacuate the combustion chamber. The higher the back pressure the lower the exhaust velocity. The lower the exhaust velocity the less vacuum is generated from the headers pulling spent air out of the chambers during valve overlap. I will agree that proper materials need to be used with good welding.

I KNEW IT!! I freaking knew it!! Had a mechanic explain this to me when I was 19. I had a 96' Police Interceptor Crown Victoria I wanted to put Dale Eastman exhaust on. I wanted to know why mine was going to cost $300+ when my boi paid around $100 for his exhaust. Long story short, I listened & let him to the job. Had duel exhaust coming out behind the wheels, & it sounded so good my pops was jealous, & he had GT Mustang with Flows on it. Mine sounded just as deep, if not deeper than his car. I just thought stuff had changed now that everyone was getting the 30 minute slap stick exhaust jobs on all their Chargers, & Challengers. Good to know. 😎🤝

What kind of exhaust you plan to put on the Scat Pack! Or are you just going to go to a different shop🤔?

Hey bro I recently purchased a 2019 scatpack and the dicks before me did a muffler delete and now I have a squeak what should I do?

Back pressure wont matter if you cut your mid muffler because you already got two resonators by your exhaust tips.

My widebody is catless, and striaght piped from the cats on. None of the factors he mentioned in this video happened to me. I did get a CEL on the dash, but that was because my air to fuel ratio was off because of the cat removal. I had my tuner that I've been working with for years, tune my car and both my HP and Torque are off the scale. I would say, do some research before modding, 2nd and 3rd opinions do matter.

Hey man love the car. I was gonna cut my pipes on my ram 1500 but waited and got the flow master American thunder exhaust and I’m glad I did

The only thing I've noticed with my muffler deletes (all) are it ships from 5 to 8 quicker at lower rpm. But it hasn't bothered me or have I lost performance.

Ok question I’m new to this car stuff if I cut my mid mufflers off my challenger scat pack will it mess with my active exhaust or does that have anything to do with it ? I didn’t hear it if it was said in video

Mechanic his whole life but called the resonators mufflers🤣

Ok I’m glad I didn’t dew mines yet wat direction should I go ?he was speaking foreign to me new to this car shot but I want a real exhaust wat should I look into?

on any charger ? What about the v6 GT 3.6 or the RT 5.7 V8?

Just cut my mids yesterday on my new widebody scat, best thing I ever did

A lot on inaccuracies and rants especially on the performance end , however value to investment perspective is on point .

So what about the tips? When mine comes I just plan on changing the rectangle tips to quad tips for the time being on my challenger. Will that effort the vehicle performance?

What’s the measurements for the side fender emblem trying to place the new ones?

I'd love to hear the school this guy went to for his engineering degree 🙌

Some say it do some say it don't. Only thing I know is I'm riding around with my mid muffler off and the reso is next 🤷🏿‍♂️. Until I get the money for a Corsa.

So what’s the best route to go for a louder sound ? ?

So what exhaust are you going to get now

So if this the case why is literally every race car straight piped? You want the most flow out of the motor thats how power is made. Im not an advocate for cutting up your shit like a loony with a hack saw but this is another one of those uneducated (ass)umptions because with a tune you should be making power off of cat and muff deletes not losing it. Especially on the top end where flow and rpm are king

If a top fuel dragster produces 8000HP with 20 inch open headers, how much HP could it make by welding the headers closed and maximizing back pressure?

Alright, thanks for the information buddy. I'll be on my way to another muffler shop now. 💯🤣

So I should get the 5 inch chrome exhaust tips ? GOTCHA OG

I did a resonater delete and replaced stock mufflers on my Mustang; I added an H pipe and Roush Mufflers. This mod saved weight and made car sound amazing.

It’s crazy cuz when I deleted the muffler and added an x pipe on my camaro I felt lighter and faster

Long story short get a wide band afr or scan tool note your air fuel ratio at all driving condition. When you remove restrictive exhaust components you'll run more lean because air is moving through more freely which can feel like power loss so you'd need to extend injector duration - add more fuel to get back to your recorded afr. This is how you get the power which is why people say get a tune.

Theirs two mufflers I want for my car. $350 each and they have to be welded on. Is it still cheap?

The man is a mechanic, not an engineer (no disrespect). The idea of needing back pressure is a myth, and he even points out no cat/high flow cat would help make power. A straight 3” pipe will make more power (MotorTrend busted this myth in a great 2.5” vs 3” comparison). And FWIW - he called the resonator a muffler…

Where is this mechanic shop at ?

You just saved me time and money. Sir, I am grateful to this mechanic for his wisdom.

Besides a borla or corsa what’s the next best option?

Mids do nothing but change tone brodie it’s deleted cats without a proper tune that hurts the car lmaoo

Yea I’m with what the guy explained.. I’m not cutting shit off my 2021 scatpack. It already sounds mean.. and when I’m cruising it doesn’t have that drone sound thinking it’s a damn truck when I’m passing by.. quiet when I’m cruising & sounds mean when I open her up..💯

So is a rear muffler/resonator delete safe?

🔥🔥🔥 I like this video!

"Tuning" for muffler deletes🤣

Thank u knock out 360 for that information 💪🏾

I had a 5.7 built and to fix the back pressure issue I installed an X Pipe.

Don't most of the bolt on systems also remove the mid mufflers and reduce back pressure? How are they any better other than higher grade materials.

I don't see nothing wrong with a mid muffler delete, my car sounds great with it, still have my cats and back mufflers,. I have no complaints. Best $100 I spent on Smurffet.

Someone better tell all the drag racers to stop running open headers. I mean they must be hurting performance with no exhaust right? Lmao

Sooooo do you lose power when you cut out resonator and muffler ?

You mentioned Dynomax. Were you referring to the mini bullet mufflers. I’ve heard about those before. Are they not legit to do?

I fell the same way, I just spent the $2,000 and got a full Corsa exhaust system. Good thing is it's a whole bolt on if I don't want to keep my Durango I can unbolt and put factory exhaust system back on. Sound is better and no drone.💪🏿💪🏿💪🏿

I have a R/T pretty sure the 392 is the same the mid muffler is just an open case no need for them but you put that aftermarket exhaust on and I garauntee u they’ll void that warranty and resale goes down

Him: Say all this 🙄 Me: cool story bro are u goin to do the muffler delete or not??? 😂

Big Swole DAWG bringing the content we need!!!

I deleted the mid muffler on my 21 scat here about a month ago and replaced it with the Dynomax Mini Race Bullets and I have noticed no loss in performance. I’m sort of OCD about that kind of thing and I would have noticed. Maybe what I did is better than just welding in a straight pipe in place of the mid mufflers. That sounds too raspy anyways. Also Have fun spending $2000+ for a full cat back system just for sound and no power gain. The 392 is optimized already from the factory so full exhaust does nothing for power.

Solid advice thank you. The pipes are being cut tomorrow.

Great video i have a 2019 challenger rt hemi eas thinking about a mid muffler delete after watching this i wont i will save money and get a borla again freaking great video thank you

Where did you get your wicker bill spoiler from

damn thats very informative....cut my pipes

Hes nuts. Its the best mod I've done so far

After watching this video my take away was where'd he get that rear spoiler? All the rest was nonsense to me. 🤣

i had got a mid muffler delete when i got my RT and it doesn’t sound like others do on videos i don’t get pops or and it doesn’t sound very aggressive

I dont think the mid deletes will cost any low end power - on that I disagree with him. Having said that, cutting the mids off the scats wont improve your hp at all, either. It is purely a sound change. Nothing more. What I do agree with him, though, is that replacing the nicely built and high quality (and not restrictive either) oem mids with cheap parts… that cheapens the car. Have you ever heard of lambos and porsches or even m trim bmw owners “cutting their pipes”? Or replacing their high quality oem mufs with cheap loud ones? No. Why? Cos thats what ricers do. If you cant appreciate the car that you bought, then return it, dont cut and patch it. Thats for cheap hondas, done by cheap ricers. (Buying a fully built aftermarket catback, is another story, I am only talking about cheapening / cutting / patching your awesome car here). Do it proper, or keep it proper.

Obviously some people just believe the BS that they are fed! 😂🤣😂

Man the race bullets are like that. If you don’t have the bread to get a full cat back exhaust. The race bullets are nice for a quick set up!!!

Say you got gapped by a loud 392 without saying you got gapped by a loud 392. 😂
