Audi A7 with s4 mufflers

[Jivoz123]

Hey guys, after doing a bunch of research and testing I found a setup that works for me.
Here’s how it goes
Baby resonators deleted (xpipe instead)
Suitcase changed to rs7 suitcase
Mufflers from a b8.5 s4 (gutted:repacked, welded one side) *insanely difficult but worth it*
H pipe added infront of rs7 resonator.

End result is
0 drone
Loud when your on throttle.

Here’s a video *hope you enjoy*

So according to my muffler guy, he cut the s4 muffler open. inside there were 3 chambers. he opened the chambers up then he repacked the muffler.

im not 100% sure what he did exactly but compared to the stock s4 exhaust on the a7 its much better.

[Jivoz123]

updated my exhaust setups incase yall wanted some info XD

[DocTJ]

thanks for your time and input

[Jivoz123]

[buggzbeny]

Why do you want to change ? Is there something bad ? Or just for fun ?

Im looking for a very unique sound which i havent found yet. there is nothing bad about my current setup. i just want more sound with no drone.

update! sounded like a gtr but there was a TON of drone..

put the baby resonators on, put the rs7 resonator back

removed the Hpipe after the rs7 resonator. (sounds like it used but a little less refined)

going back for more exhaust work on wednesday

If you're still itching for a bit of growl, consider the Remus mufflers. Here is my car. Objectively, this is how the A7 should've sounded from the factory.

im honestly trying to go as loud as possible with 0 drone, so far im on the right path

[Spartan3985]

I will be following this as much as possible. I am literally looking for the same thing out of my A6. I think she deserves a much louder presence than provided by Audi. Please keep me posted because I love where this is going. Any way to get specific details from your exhaust guy about what was done with the S4 mufflers?

[Jivoz123]

It’s hard to describe exactly what he did because I wasn’t there, but from what he said

He opened the mufflers, inside there were 3 chambers, he took out 1 chamber and pretty much straightpiped the 2nd one, then he repacked everything with steel packing or whatever and closed it.

We tried doing only s4 mufflers but it sounded 100% stock

[Spartan3985]

So by removing one of the chambers inside the mufflers, this is what opened up the exhaust? This is not a criticism, just a question...Wouldn't that be the same as adding a 2 chamber muffler like a magnaflow/flowmaster etc 2 chamber? I dont really have much exhaust experience other than with my former mustang but that was litterally straight piped from the headers back to 2 chamber flowmaster mufflers. A car like that doesnt drone so that wasnt a consideration I had to worry about.

i tried magnaflows and flowmaster super10s..... results were absolutely terrible.. sounded like a honda.

opening up the chamber completely changed the tone of the exhaust, now it sounds refined and the videos dont do it justice. the car is loud with 0 drone which wasnt the case with the magnaflows. also the magnaflow mufflers are very small which could be the reason they created so much drone

Hey, long process but appreciate keeping us posted, I have a couple questions though:
1. baby resonator delete and replaced with non resonated xpipe
---what is a baby resonator? I've been under my car, also doing multiple exhaust changes, to achieve the same goal as you (load but little/no drove).
2. hpipe added 5-8 inches infront of rs7 resonator *deepens sound*
---I am running resonator'less, factory "X" pipe still in play, is yours?

Do you have pictures of the underside showing 'baby resonator delete' and 'hpipe' addon??

Thanks in advance. Today I welded in a single cutout, dual like before would drone like crazy, single isn't too bad but still not what I had hoped... my exhaust guy worked on my exhaust 6 times, he laughs when I come back, but he's super flexible and patient with me haha.

I'm about to throw in the towel and order the Magnaflow kit (but will remove the resonator), unless I can find out what Magnaflow mufflers they're using but the website won't say unfortunately.

so the baby resonators are the little bottles right before the factory xpipe.

the hpipe is right after the rs7 suitcase resonator.

ive tried magnaflow and didnt like it. go with vibrant performance. they are much much better

I've had the Vibrant Performance Resonators, used two of those to replace factory suitcase... I had them in with no rear mufflers and with 2-Chamber mufflers, didn't help much, removed the resonators and the 2-Chamber mufflers and put it back to OEM. Before today I went back to suitcase delete and OEM mufflers and like I mentioned before I just did a single cutout.

Here is my OEM exhaust, possibly different since you have a 2018 whereas mine is 2015?
142836

So maybe, using the picture as reference, I don't know what the baby resonators are because our exhaust is different?

[Jivoz123]

Exact same setup, but my pipes are from a rs7 so mine doesn’t have that factory xpipe

[Jivoz123]

has any1 tried vibrant ultra quiet resonators in place of the suitcase?

considering doing this if no1 has tried it.

Is that an H pipe before the suitcase?

[Jivoz123]

its a "xpipe" but mine isnt there as i have the pipes from a S7

[tuscani66]

Yes, I installed two of them (for each pipe):
1. was straight piped, installed 2 resonators to control rasp, failed.
2. installed two Flowmaster44 to the original OEM muffler location, maintaining the 2 Vibrant resonator, didn't achieve the sound I wanted nor help with the rasp 'enough'
3. removed the 2 Vibrant resonators and put back the 'straight' pipe(s), maintaining the Flowmaster44's, too loud but not deep.
4. removed the Flowmaster44's and reinstalled the OEM mufflers, maintaining the suitcase delete, accepted it for what it is (a little deeper and louder than stock).
5. I've done other things since but just wanted to answer the Vibrant part.

[Jivoz123]

I think ima try vibrant ultra quiets, with the s4 mufflers

[edwrds4]

when you say theres no drone, is it like dead silent in the cabin or can you hear something...

alot of people said no drone with the suitcase delete but when i did it i couldnt have a conversation inside lol

there is absolutely 0 noise inside. and even on wide open throttle it isnt that loud. from outside it is noticeable and turns heads. but that might just be my intake XD

[Jake_a]

is there anyway for you to show us what the muffler guy did ?

[Jivoz123]

sorry for the delayed response, im going back to the muffler shop next week. i will have him cut open the muffler for some pictures.

[Jivoz123]

just a quick update. we installed flowmaster outlaw race mufflers in place of the suitcase. sound was very very deep but VERY annoying inside.

Hmmmm thanks for update

[Jivoz123]

Hmmmm thanks for update

Im not sure if you have the factory mufflers from the sq5 but if you did I’d say try to retrofit them😬 that’s my next setup

[Spartan3985]

So my whole exhaust project is on hold pending the results here. So far I'm looking at downpipes, suitcase delete for x pipe with s4 mufflers modified to 2 chamber. Looking for loud, not obnoxious but loud. As for drone, can't a little dynomat or something similar in the tunnel take care of the drone issues? Thoughts?

[Jivoz123]

I took out everything

As the car sits

Stock baby res
Center replaced with 11385 magnaflow
S4 mufflers

I think something broke inside the s4 muffs
There’s a ton of rattling
———————
My next setup is going to be with sq5 mufflers and a single 2.5” exhaust similar to a r35 gtr

https://youtu.be/3o5LTzr0aaI

This is exactly the sound I am looking for. So the remus mufflers were modified? Thank you

[Jivoz123]

He just swapped the factory mufflers for Remus ones, very easy job should be less than $100 for install

[Jivoz123]

update for those who care

previous setup

s4 mufflers gutted and repacked with stainless steel packing

11385

rs7 baby res

drone, WOT sounded like a gtr tho



current setup



s4 mufflers (not gutted just stock)

magnaflow 11385

stock baby res

car sounds 100% stock with only a burble on shifts.

so now youre back to stock mufflers with res delete and magnaflow X pipe in place of that?

[Jivoz123]

correct


stock s4 mufflers not a7

11385 in place of the suitcase

and stock downpipe resonators.

Thanks to update this post with all your experiences. [emoji6]

Can you put the pictures of modified s4 mufflers ?

What about SQ5 ones ? Do you still want to try it ?

anything with Xs are removed and filled with stainless steel packing

Yes, please do. I picked up my A6 a few weeks ago, and like many others, I'm trying to figure out how to give the exhaust a deeper note and growl, while not having any drone in the cabin. I have a used set of S7 rear mufflers with valves that I plan to mount, but I'm sure that will do little to change the note. Any advise is appreciated.

[Jivoz123]

bump for others

[f4m0u5]

Im looking to find a soind loke this with aftermarket equipment. Its hard to sourse a rs7 suitcase and s4 mufflers rather then having specific aftermarket muffler/resonator combo.

Not sure its even possible but i love a clean sounding exhaust so i will be experimenting a little also. Just not with stuff u need to find used/ rework.

As of now just center suitcase deleted is horrible at certain points legit sou ds like a damn honda with a fart can on back....
Not sure how with stock cats, stock resonators, and stock mufflers it could have this sound......






Does any one know if the s6 and a6 have same size spot in rear for mufflers? If so maybe just a track to touring conversion kit would fit perfectly from a s6/s7? Its like 650$ for just the rear mufflers but are a known good sound.

[Jake_a]

any new changes in your a7 ?
