I remember when I was about 5, my dad was changing his exhaust out for a flowmasters one and he started it while it was straight piped...let’s just say it scared the shit out of me 😂

The amount of guys who spell it "Vortex" in instead of Vortec amazes me 😂

When someone pisses you off, pass them and tap on the gas once you’re next to them😂 I do it when someone’s texting lol

I think that it with cats sounds cleaner to me

Straights with cats gets my vote. You should post a vid with the Magnaflow.

Getting 2.5” cat back striaght pipes put on with 5”x18” tips. This video was very helpful even though I knew I wasn’t cutting my cats off. Very good reference and the audio is good.

You have inspired me with my truck I have the exact same exhaust setup as you dude! True duals, straight pipe, no cats & no muffler 3.5x18 chrome tips. Thank you

Solid video man! I think both sound good and I love the sound of the 350 Vortec. At the end of the day, I would probably choose the cat back set up just to reduce drone. But, it's all a matter of how much drone you can deal with as well as if you want to be heard a mile or two down the road lol

Finally someone with the exhaust in front of the rear tires that's how I want mine

awesome video man! the last video was epic!

Loud pipes 'save lives' (and keep other drivers - who are driving while staring at their damn phone - out of your way!)

All you need is a big cam and you've got a muscle truck!

both sound great man! I have a 95 f150 with true dual straight pipes and no cats so I'm addicted to the pop and rasp of no restrictions lol

love the vid my truck (98 GMC) is very very similar i have thrush glass packs and taking off my cats after watching this. just subscribed and i'd love to see what else you've done to the trucks!!

With cats it’s a lot less raspy and less “farty” sounding. Much more of a smoother tone to it :/

Great in depth video man!

Love the 350 got to see one in a 99 Yukon this mornin, if I end up gettin a Blazer or S10 I'll swap a 350 into it for the mud truck.

I couldn't agree more with this video. I've had both 'cat back' straights, and catless straights (both on channel), and I feel pretty much the same. I ran with the cats for years, and the catless straights lasted a month or so. It's just too much. I constantly had a headache, and everytime I left a stop sign or red light people looked at me bad. I even scared an old lady on the phone one day so bad, she forgot to take off when the light changed, and just stared at me. Granted, she shouldn't have been on the phone anyway lol. Plus the constant fear of being the loudest thing in the county, and knowing you were probably gonna get pulled over any second. I mean, don't get me wrong... IT'S FUN...but not worth it, especially if it's your daily driver. I recently switched to thrush welded mufflers still without cats, and it's so much better. I actually can drive the truck and feel somewhat normal again, but WOT if I want the straight pipe sound. Also adding the mufflers made the truck feel like it had power again, though the cat removal didn't really effect my truck much. Great video man! I'm 100% with you. *Fun, but too much* That's a nice obs Silvy you have btw!

Wicked truck man! I have the exact same one ! I see your from Alberta same here ! Thanks for the help

That was a very helpful video, I think I'm going to run a 2.5'' no cats set up.

They both sound amazing!!!

I was the same way haha. I had true dual straights with no cats for a week and got tired Of it. I'm actually buying 2 magnaflow hiflow cats to do cat back straights soon.

My friend has one of these and he’s planning on straight piping it, can’t wait till he drives that thing to school lol

What a sweet looking truck

3:58 the 350. Then the random truck. The 350: proceeds to make more noise farther away with less than half throttle. Pure gold!

I did 2 1/2 inch true duals on my 350 vortec no cats with an h pipe both exiting at the side and it’s actually pretty manageable inside the cab is quiet and idle is quiet sounds amazing under acceleration

love the vid man, Alberta pride

Nice video, for my truck (1948 dodge 1ton, so will be a hot rod that i plan on daily driving) im doing double exhaust, so building it like a semi and have little 2.5 stacks on it that will be straight piped. Then going to buy an exhaust valve and have a long set of glass packs (longer glass packs=less sound) for when i want to say just enjoy the ride and listen to the raido or be able to talk to the person next to me. (im sure the straight pipe stacks right behind your head with just a layer of sheet metal and boom mats is gonna be loud inside! )

Very helpful video. Thanks

I have a 96 silverado and I have it straight with cats and a y-pipe on the end but want to run it out of the sides but want to do it as cheap as possible but still sounds great would you recommend using tips or just pipe?

Straits with no cats....the only way to have em ......time to wake the neigbors

Man that sounds FUCKING SICCCCKKKKKKK !!!!!!!!!!!!!!!!!!!!!!!!!!!

Awsome video man

Got a 3/4 same silver. Turned down after the cats. Its loud but thats how i like it! Sounds way different cause mine dont go out the back. You wouldnt want to pull it hard all day, it would be exhausting. Ha

Hey what wheels and tire setup is that I really like them not the stocks but the chrome ones what are thanks in advance

Straight truck! I like the additional lights on the tool box!

That clap without cats 👌

I love the roar it has without cats, sounds more like an old raggedy muscle car

nice video this helped me alot thx

Thanks for this video

Do you still have to run the O2 sensors for the computer and if so do you have to do a relearn or re tune

When you deleted your cats did you have to tune your truck to make it not throw a engine light or did the truck not care? My cats are shot on my 97 suburban and am going to delete them but just wondering if I need to get it turned. Thanks!

With cats has that sound that only GM can produce and it’s legendary

2:07 my favorite sound by far

well maintained tbi 350’s not only have a cooler tone, also are louder believe it or not, no-tecs with duals talk to ya but not like them tbi’s with the tv cable set correctly , i love me some double down shifts with dual shit pipes😎

Hey what's the wheel size and brand and style called in your no cats portion of your video? I'm wanting new wheels and tires on my truck and i like how yours look.

nice video..same had cats off for a week..good for me bad for family run around putting high flow cats

Ha sounds pretty rad without cats but I agree it would get super annoying by the second day. Personally I would just go with a 14" magnaflow and keep the cats. Nice and quiet when idling but awesome purr with throttling.

2:07 perfect👏🏽

The one with no no cats sounds better if you have bigger tips and it just depends on what size pipe you ran to

So what if I cut my cats and kept my flow master would it sound good?

What are the aftermarket wheels on this truck?

I’ve got a 96 z71 pipe is cut at the back of the cab. It’s a y pipe to the single cat and 4 inch pipe from the cat back. Anyway I’m assuming the cat is still intact cuz no codes (I just bought it from my dad who bought it from some kid) but the original Vortec 305 has been replaced with an 880 4 bolt main 350. That said your truck sounds absolutely obnoxious on video without compared to what mine sounds like with cats. In fact I had a 305 put in my nova which just had a one foot pipe out of each manifold that was pretty quiet unless I floored it. I assume it’s either your audio quality or the length of pipe on yours. I normally don’t like straight pipes on a 350 but mine seems to be just the right mix of quiet at idle with loud under load, I want to keep it straight pipe, but gotta have a muffler around here or get a ticket. Looking to find a “muffler” with no filler. Thought about finding an old mostly round cat that’s been punched and have it welded in as a “muffler” anyway thanks for the video!

How did you bypass the O2 sensor after the cat? My 97 has 1 before the cats & 1 after. Does that mess with the performance other than mileage??

Exelent video. I have a big block 496. Straight piped with cats.

I drive a 98 k1500 with a vortec 350 all orginal i love that truck im thinking of straight piping it

Does it have much of a smell after installing the cats?

Just thinking if it's worth Straight Piping my Silverado 96 5.7L and getting tickets... the thing is how would I turn off the o2 sensor in the Exhaust?

How did you do no cats without o2 sensors messing up? I have the same thing as you, true dual with dynomax ultra flow X muffler with dual cats and I'd like to get rid of the cats

That is a great looking truck. I have a 1993 Z71 xcab with 326,000 miles on the clock. How did you get the auxilary lights in your tool box to power. I like them. Great truck and video.

Ever get picked up without cats ? Sounds good!

Nice Video for a Yank! I love the Truck tho!Props to ya...I have a 1997 Chevy Z-71 K1500 With a Badass Dogleg 4X4 sittin on Mastercraft Courser Mxt 35’s breathin’ on Dual Flowmaster 44’s and Straight Dumped before the Ass ends.No problems at all down here in Beautiful South Alabama,Brothers! Roll Tide Y’all!!

Great video

What inch pipe do you run?

This might be a stupid question but I currently have glasspacks on mine but I am going to be putting an offroad y pipe in place of my catalytic converters. Will it get a bunch louder?

I've got an obs k1500 with a 350 like that. I'm going to be putting mid length headers on it with true dual straight pipes no muffler, no cat. Should i go with 3 inch or 2.5 inch tubing and what size tip would sound best? I want to be loud but I hate that crackle that most chevys get with straigh pipes and I'm having bad luck finding good videos. Any help is greatly appreciated

I have a '97 Tahoe, with true duals, no cats, with a Magnaflow 2 in 2 out 2 1/2 , with the tailpipes 45'd out the back. Much less cackle, more of a deep tone! And it's not a Flowmaster! Lol

I'm running a 97 GMC no muffler and it's cut off under the box. It's decently loud, thinking about running the side exit like you had done. And I'm probably gonna hollow my cats out. You should post an updated tour video of your truck, looks and sounds pretty sweet!

Wish someone could do a video like this but for a tbi

Nice truck

I like straight with cats, mine is no cats with flowmaster 50, Its nice growl not raspy or overbearing, sounds like a truck should!

Do u have a lift kit on your truck

Is there a lot of drone or no

Would someone please enlighten me here? How are you running dual straights, without catalytic converters? How do you manage to bypass the O2 sensors and everything still runs? I have a 98 Z71 Sierra I am wanting to do this too. But, I have 2 catalytic converters of course. One on each side. And each Cat has two 02 sensors. 1 before & 1 after the Cat. How do you bypass those & still have a functioning motor?? Thanks!!

What are those rims called

So what better straight pipe with muffler and cats or straight pipe with muffler but no cats I have a 1998 Ford F-150 flareside triton v8 5.4L it has the power to make a lot of sound whenever I rev it you hear more muffler than engine which most new nowadays all you here is the engine it had the power I just need to unlock but idk which way I want to go about doing it I also wanna add a lift kit to it some nice rims and tires and a bullbar in the front it’s my daily driver so I want something that get me notice and is throaty and loud but not to loud that I wake up everyone in my damm neighborhood plz if you have any suggestions pls let me know

i have a 6.0 powerstroke and idk if i should get a catback exhaust or a full straight pipe. The straight pipe sounds better but I'm not sure if it will pass smog. What do you think, anyone's opinion would be appreciated.

Was going to do no cats, but too loud. My MBRP catback is plenty, sometimes too much..

I like straight with cats. It's more muffled and sounds a lot smoother while still sounding really bad ass.

What size pipe?

Yay Alberta!

Is the back of your neck a reddish color. It’s dual not duel

Straight pipe!

Lol my first truck wasn’t true dual but with a y pipe that turned into duals, but I didn’t have a cat or muffler so it was still loud and obnoxious 😂

I wanna do cat back straights on my obs

so I got a 96 Tahoe the exhaust is junk want to pull all off and go cheap how do I turn off 02 sensors? ? I've been told the milage will go from bad to worse if you just get rid of them???

those tight chambers left open.. one would need a bigger overlap cam to enjoy the open pipes. Same for the L30(305 metric). The last of SBC mentality.. hate to see ya kill it. I have killed several and regret it. 200cpi cat, and flowmasters. Injection computer doesn't get jostled that way. Ignore the low HP comments, those are culted honda drivers. My "little" L30 is 280hp to the ground.

I think you should keep the straight pipes that go to the back of the truck but with cats

Lose of torque is that you lost all back pressure. That why we ran 2" manifold back with 3.5"x18" tips.

With cats dose it get that loud in the cab of the truck?

How do i take off the service engine light? Do i need to get a tune? Bc i deleted my cats

U from Edmonton eh, I recognized spots in this video

I got a 5.7 and I’m going to straight pipe it

they look nice

I love that shit sound good

Will it effect my truck to start up?

How you cut them off and keep engine light off

With out cats sound so gud

It's funny cuz my pipes are shorter and probably smaller and the quadrajet I have on it must not be pumping enough to make it loud. It's kinda quiet tbh.

That's good bc I got a 98 silverrodo 1500 single cab long bed with a 305 small block and it'd my first vehicle I got it for $300 atleast I know what to get and nice truck there eh
