Sorry for the slow reply. Just saw this! I did exactly what you are thinking of doing. We put RBF 600 in there and it was a HUGE difference. That said, it is still pretty easy to over heat the brakes. Mine got glazed pretty badly after a few times on the track and they lost a lot of stopping power and would heat up pretty quickly, even on the street. I'd say if your brakes are about 50% and under, go out there and have a good time and just get some seat time. If they are fairly new, it might make more sense to look at another option that would hold up better at the track rather than destroy your stock set.

@@thekrogmanman thanks for your insight, let’s see how far my tax return can get me 😂😂😂

It's exactly the same concept. The 034 unit is just a pre-bent pipe with clamps. Otherwise you're going to a muffler shop and paying them probably the same price to weld a pipe in. Unless you have a pipe bender.

don’t know what ur talking abt

Did you ever find out what this is. It's like a "wooo-ing" noise

no

I wouldn't know exactly since I don't know CA exact laws but I bet you'd be fine. I've heard much louder cars in CA. The car really isn't very loud with the resonator out. Just about 20% - 30% more noise I would guess.

I don't think they are obnoxious. It's subjective really, but they were really pretty mild. I thought it was a good balance of a mild exhaust when you drove easy and just enough sound to feel like it is sporty when you are driving spirited. The only time I dont really like it is when you are driving through the neighborhood with the engine cold. I thought it sounded a little ricey for about 1 minute of driving.

@@thekrogmanman thanks for the reply! that's good to hear. the example video on 034's website make it seem like the DSG farts are SUPER raspy, but other videos they seem tame so idk what that could be. but yeah I have heard when its cold, its a little... Honda Civic-y haha. Overall do you think its worth it? I want something subtle, but sporty. my car is also a daily driver. Would prob also pair it with the 034 intake.

@@boostseason That's exactly what you'll get. My car was tame enough for clients to ride in. The intake will add even more noise than the rest delete. I cut my airbox and got some turbo noise but not a ton. Same goal, comfortable daily but sporty when you want it to be.

@@thekrogmanman awesome - thanks! plus its such a risk free/reversible mod that even if I don’t like it, it's easily reversible.

@@boostseason Totally. I'd have a muffler shop do a welded one though. The clamps aren't great.

There aren't any sensors on the OEM resonator so I don't think it should have any effect at all on emissions. It's just designed to remove a certain frequently of the exhaust note.

@@thekrogmanman I hear that, my concern is resistance released might allow more flow? I doubt it’s drastic but I’d be concerned.. cheers anyway.

@@blizteredthumbs7911 I haven't had any issues but the UK could be different. By the way, normally I recommend just going to a trusted muffler shop rather than doing the bolt on 034 Motorsport option. That said, it might be a good option for you because it would be easy to swap back if you had an emissions issue.

@@thekrogmanman all good, nothing done at present, more curiosity playing havoc with my brain 👊🤪

That's what we have in the US too. You remove the first one right after the downpipe. You can do the 034 Motorsport kit or just have your favorite muffler shop do it.

@@thekrogmanman Thank you for reply! Do you know What are the difference between the first and second one? Or which one have more resistance？

I don't, but there are videos online showing both mufflers deleted if you want more sound. I think it sounds good but probably too loud for me.

@@thekrogmanman Hi, how was the sound while accelerating from low rpm? (without down shift) I just did a muffler delete, but the drone is killing me when engine is under load below and around 2000rpm, now I'm considering put the mufflers back on and do the reasonator delete. Thank you!

If you have a similar Audi, it will give you an idea of the exterior sounds it will make with these mods. If you don't, it's a waste of time for you. It's a pretty short video though

There's an interior video on my channel also if that's what your looking for.

I have the same audi a4 b9 with valve custom exhaust it sounds nice

Haha! You got it!

Quattro

No, the tune doesn't add any DSG burps/farts. The res delete makes the stock burps a little louder. IE has a crackle tune for some vehicles but not the B9 A4.

@@thekrogmanman oh ok any idea on how to get them I really like how the gti sounds but don't want to spend 1k+ on an exhaust, thank you.

Res delete makes them a little louder. Or you can remove the mufflers. Search videos of that and see if it's something you like.

@@thekrogmanman Yea I have seen them still not DSG noise on shifts which is what I want.

@@thekrogmanman At 5:54 seems like your car made the noise when it shifted but not sure tho.

No, difference in power of any kind. It's located right in the middle of the car right after the downpipe.

This is just the Premium model. No valves on the exhaust system.

B8s weren't out yet. I'll be putting B8s on the front soon. The B6s work great in the back though. :)

@@thekrogmanman thanks. If you could compare clearance after switching to b8 with the same springs.

I'm going to keep the B6s on the back and put B8s on the front. The ride height didn't change when I went from stock to B6s. I doubt it will change on the front.

Just the front resonator

Bro I did the res delete on my b9 and it sounds great. It's not overwhelming, but it adds german growl.

Yeah. I have a list of upgrades but not many that affect the sound. Stage I tune from IE now, but I didn't have it in this video.

@@thekrogmanman Any reason why you didn't go with APR?

@@_Mario_PL_ just the research I had done. APR sounded a little more aggressive than what I was looking for. IE has a good balance between power and reliability. Also, as a bonus, they are local for me and I wanted to support them.

@@thekrogmanman thanks for the info. I have 2018 A5 Sportback and still not sure what to do. Been stock for 2 years and I think it's time to play a little.

55% of the exhaust sound suppressed by the front resonator, less than 5% on the middle resonator and the rest the rear muffler. Delete accordingly

@@cobaltpica Oh ok thanks man! I already deleted my front and its way louder than stock but only under WOT. Still looking to make it louder but don't wanna delete the rear muffler cuz it'll be too loud :/

I agree with Redember Black. Glad you like the sound of the res delete Nick!

@@cobaltpica Thanks for this info! I had a custom downpipe welded with a Vibrant Ultra Quiet and I'm thinking of completing the rest of my exhaust system. I think I will just completely remove the rear resonator and replace it with Flowmaster DBX instead of having 2 mufflers. Would that be too loud?

@@cobaltpica Hi! Thank you for the information, do you know which part in B9's exhaust system have the most resistance after the cat? I was wondering to keep the front resonator, replace the middle one with a valved muffler, and remove the stock tail mufflers. Do you think this set up will make sense?

I wouldn't know for sure but I'd say it's probably about the same if there is one resonator on that system. I bet the rear muffler is about the same amount of noise reduction as the dual mufflers on the dual exhaust setup.

thekrogmanman I have an 09 a4 and it has 2 resonators I’ve seen vids of it removed but it sounds like a fart can all the premium systems are expensive af and they sound decent I like how an s3 sounds but idk if it’s possible to get that similar sound on an a4

@@thenotoriousjoey9956 ahh, I wouldn't know as far back as the 09s. Sorry man.

thekrogmanman guess I’ll have to pay up on an exhaust 😔

@NutriFIT nutritie si fitnes ill give an update on that lol. Having a single resonator delete and deleting one muffler and going with a Flowmaster about mid car..

Yes. Good eye.

Hey Nick, yeah, center resonator removed (only resonator on the A4), the mufflers on the back are untouched. It has a stage 1 tune from IE, k&n filter (no intake), tranny mount, springs and end links from 034 and cosmetic mods: RS grill, CF mirror caps, debadged, etc. I'm sure there's a few more I'm missing.

No intake. Just k&n filter.

No, there is only one resonator on the b9 A4. It's in the center of the car just off the downpipe. That was removed. The rear mufflers are still in tact.

@@thekrogmanman thanks for answer, maybe in your country a4b9 have only one. but for my country (russia) they goes only with two resonatores. but actually u have just two muflers and no more?

Oh, for us we have a resonator in the middle of the car and two mufflers on the back.

@@thekrogmanman now ill know it because of you, thanks! "russian" a4b9 have 249hp, but in your probably 252hp. All because of our laws and taxes :(

@@user-st6ot5jr7v yep, 252 hp over here. :) Maybe that extra resonator costs 3 hp? That's not bad.

Nope!

Thanks! It's pretty cool to have those pops with just a res delete! Wish they happened a little more often.

Yea agreed just some more pops will be amazing

Do you change the front or the middle resonator ?

@@Andre-yq8sd on the A4 there is only one in the middle of the car. The two rear mufflers are still there.

No I don't. At the time of this video it only had 034 MotorSport lowering springs. It now has adjustable end links and Bilsteins in the rear, stage 1 and a res delete. All other mods are cosmetic.

Thanks man. It was a blast.
