2013 Audi S6 and Muffler Delete Exhaust question

[AudiTurbo4me777]

So I went in to remove my remaining center muffler as I already removed the rear mufflers thinking it would be alot louder. I also put an X pipe in place of the center muffler so I'm all straight pipes EXCEPT for the 2 front resonators. Funny I would think it would be much louder after that but in the end it was just a little bit louder but does now have a deeper tone. Does anyone think If I removed the 2 small front resonators it will get much louder? I was going to put bullet mufflers on the back straight pipes but probably just make it quieter.

From my experience, the two front small resonators would not make much of a difference.

I too have a '13 S6, can you post a video ? I'm very curious.

I had a 2016 with the sport exhaust and after I replaced the center resonator with an X-pipe, it sounded amazing (like a Mustang mixed with a Lambo). Our '13's didn't have the sport exhaust option, and are very quiet cars. I'm surprised to hear you don't find it much louder without the rear mufflers or the center resonator.

on my 16 i went straight through on the center suitcase.. sounds insane, imo (with a tune making a difference?)

As small as the two front resonators are would make sense they don't do alot to the sound but the other video's I saw on youtube with an X pipe and no resonators were very loud. The first video I post will be the one that sounds exactly like my car and the back looks identical but I believe it's a S7. I will probably just delete the two front resonators later on because I heard that an X pipe helps eliminate or reduce drone anyways.

Here is an S6 I believe with no resonator, all mufflers deleted and an X pipe and it sounds so very loud. Forgot to add I think why it's also louder because it doesn't have a factory downpipe* but it is also a 13" S6. I don't think there is 50 state legal downpipes so I can't change mind(Bummer),

Lol, when I put my car in,"S" Drive mode the exhaust note definitely changes and a bit louder. Can't do anything with valves as all my mufflers are deleted

[AudiTurbo4me777]

Does anyone think upgrading ECU software to Stage 1 or higher and adding a cold air intake will help make the exhaust any louder?

Are you saying with no valves in your setup the change from D to S changes your exhaust tone?

[Audibellybutton]

the tune will make the exhaust a little louder just from the revving and output but no the intake will have no effect on exhaust sound. it will have added air noise though.

it wont make your car much louder than it is right now if thats your question

[MattyMarkey]

You must love loud exhausts. Maybe I am showing my age, but I removed the rear mufflers on an OEM sport exhaust (center suitcase is different) and it's plenty loud for me. DP's would be your only option to make it louder, and it sounds like you cannot go that route being in CA

No concerns with loud exhausts in the San Francisco area?

[AudiTurbo4me777]

I definitely noticed a little change in exhaust note. That's what it felt like with straight pipes and X pipe, No Valves.

[AudiTurbo4me777]

Lol, I'm old but i still love a nice throaty growl! I hear so many loud cars around my neighborhood guess it isn't an issue

Yeah, I was thinking by changing the tune it would make the exhaust a little louder. More air and fuel should equal more bang which in turn should create more noise. Too bad I can't change to aftermarket DP's

[aaronsananikone]

I went through 3 different exhaust setups and can tell you that the front small cans don't make a huge difference when removed. The only BIG difference really came from aftermarket downpipes. However if you go downpipes, be prepared to have valved mufflers otherwise it is offensively loud. I have quarter click valved mufflers so for daily driving I usually drive with only one click of the valves open, as mentioned full open is ALOT of sound and I generally only completely open the valves for show/go scenarios.

Well I mean you can you're just not supposed to.

but yeah I would keep the cats on there if i were you in this situation, might create more headache for yourself than you want to deal with by removing them.

As for sound, I'm the same way. I dont like obnoxiously loud. But for a twin turbo v8, I want it to sound like it has some presence. Like its supposed to. Something subtle but intimidating and low rpm. And a nice roar when I get on it. I think catless downpipe+ only rear muffler delete is prob my fave sounding custom setup for these cars. I think just a rear muffler delete is too quiet.

I think removing the resonators changes the exhaust frequencies/tone to allow some rasp I dont like, thats just personal opinion though.

downpipes (GESI units, in my experience) flow consideranbly more, sound slightly louder and do change the overall effect. with the suitcase removed and straight thru, the sound delta is palpable. In D mode it is only a deeper exhaust note - In S mode it is insane. Cheapest exhaust I've not bought, but kinda did.

added RS oval valance/finishers and ditched the uneven-by-design quad oem tips too.

if it's possible, they are even more sonorous.

Lol, If I get some downpipes and definitely thinking about it, as long as i'm not on it too much shouldn't be too bad except for maybe cold start. Did notice though when my exhaust(engine) is nice and warmed up and I get on it hard it barks pretty loud

I just removed my rear mufflers and holy hell it sounds perfect to me.

Do like your tips and yes removing the rear mufflers make a pretty big difference. If you want to go a bit further than remove the center muffler or silencer. I have an X pipe in place of mine and may just go straight pipe there and see how much louder I get. I heard that an X pipe tones down the exhaust some so straight pipe should change that

so did you end up with the rs7 mufflers in there? where did you source the valance?

Was able to just cut the oem tips off and get them to fit the ovals. I had access to RS mufflers, but its not clear if they'd be better (the valance is based off of the S line A6 i believe)

looks good. install was simple pop out and reinstall for the valance, or lots of fitment issues?

never simple, but do-=able to retain oem appearance.

My friend removed everything but the cats and it was only marginally different in sound. I removed my cats and primary resonators on the mid pipe. And got more sound from my non sport stock exhaust than my friend going straight pipes from the cats.

I started my exhaust mods with a Magnaflow cat-back and that was ok but not really too much louder from the factory sport exhaust. From there I installed catless DP’s and that was a bit better. Next I removed the resonators and that was a bit better still. Then I removed the stock suitcase muffler and put in the ECS X-Pipe leaving the Magnaflow rear mufflers and I am super happy with the sound. On cold starts it drones a bit but after it warms it sounds throaty and the pops and bangs are awesome. At WOT it sounds fantastic and I can keep it quiet when it needs to be.

[AudiTurbo4me777]

UPDATE:

So now after having the X pipe in for awhile I decided to remove it and go "Straight Pipe". Just wasn't getting any good noise above 2k rpm and the X Pipe would smooth out the exhaust sound and wasn't as loud. Now it's just all straight pipe except for the 2 small resonators in the front. I kept those so I didn't drone at highway speeds. It's much louder now above 2k rpm. I will get a video made when I get a chance.
