Who's deleted the suitcase muffler off their A6 3.0t?

[John442]

Agree with above
1. straight pipe (no CAT / no suitcase muff / no dual rear muff) = VERY VERY LOUD
2. partial straight pipe (no suitcase muff / no dual rear muff) = VERY LOUD (personal experience and lots of drone, drone is slightly less if driven in dynamic and sport trans... drive it in comfort mode will piss you off on drone)!
3. no suitcase muff = deeper note, noticeable on cold starts, small difference warm start, small difference warm car drive (but noticeable and also personal experience)

I posted videos, I went to the exhaust shop 2 weeks almost every day to try every stage, expensive...
1. remove suitcase muff, replaced with SS304 straight pipe - liked it but not enough for me
2. remove dual rear muff - loved the cold start, hard accelerations (driving manual mode and in sport), hated the drone (I have a few heavy modded sports cars, I can handle drone, this I could not)
3. install high flow resonators where the suitcase muff was (didn't really change anything)
4. install FlowMaster44 mufflers (changed the sound too much, not what I was going for)
5. removed high flow resonators, replaced with SS304 straight pipe (helped with the sound but not what I was going for)
6. removed FlowMaster44 and reinstalled OEM mufflers (back to square 1)
7. bought two 2.25 electronic controlled bypass cutoff pipe/valves... this will help me achieve what I want when I want it, wish I did this in the first place (did not install it yet though, later this month as I left town due to work for a few weeks).

So what was your final setup that you like best?
What produced the best sound.

Cheers
John

Anyone has a sound clip or describe the sound of catless, magnaflow resonated x pipe, no suitcase and with rear muffler

[Jivoz123]

this isnt a suitcase delete but worth showing it anyway








deleted baby resonators / replace with xpipe
rs7 suitcase
s4 mufflers repacked/gutted/rebuilt
hpipe after rs7 resonator

Dude... this might be my favorites sounding 3.0T exhaust I've heard to date. If you could get more videos of the exhaust from outside that would be awesome.

When you say you repacked/gutted/rebuilt the S4 mufflers... what did you mean?

And how the hell did you source the RS7 suitcase?

Any pictures of the exhaust system on the car from underneath?

Has anyone ever tried Car Chemistry Baffle inserts on a muffler delete set up? Im leaving mine alone but love the exhaust and supercharger whine! 465 hp doesn't hurt either

By the way I got Stage 2 United Motorsport tune this weekend along with a open air intake.

FWIW I just did the rear muffler delete and added single 3" oval tips on each side. Running stage 1 APR 93 Tune sounds great especially in dynamic mode slight drone mid 4th until you reach cruising speed, then it's gucci. I'll post a sound clip for ya later this evening and let you be the judge.

Lmao hell yeah John! That video of your car is what ultimately helped me make the decision to delete only the rears...sounds so nasty. Easily the best $100 I've spent since purchasing the car in November dude. Didn't have a chance to get a video last night but I'll get y'all one this evening.

How’s the drone under normal city/highway driving?

In town it's not a problem. If you shift manually you can avoid the drone.

I always struggled with the space required for cutouts. Where is the other cut out placed?

This is about the best sounding modified stock set up I've heard... just delete stock mufflers and NOTHING ELSE

Little late on this reply, but i appreciate it haha. Still sounds great to this day. If you delete anything more than just the mufflers, its to loud IMO. Muffler delete, gives you just the right amount of UMPPFF when you're stepping on it, but its not obnoxious.

[flyfishing]

Not a7, but my wife's 3.0 with same engine. This is oem mufflers, suit case deleted, front resonator deleted + magnaflow x pipe muffler installed. There is NO drone and I'd say 10-15% louder at normal driving and nice sound at WOT. Perfect for her car, but too quiet if it were mine :)

[b8_Jeff]

Reposting my Rear muffler delete on my instagram for anyone who wants to hear a sound clip. i replaced the mufflers with straight pipe + tips. My instagram is " Audi_Sith6 ".

[edmondhk]

Is there any cut-out set up which have no drone at 1900rpm?
I watch coupe of A7 muffler delete in-car video. Which tends to have drone at 1900rpm.

[Nor_Cal_Driver]

Dumb question maybe. Would this provide the same results on a 3.0 S4?

I could only fit one. does the job.... when cutout open much louder than AWE touring exhaust and burps on upshifts... lots of fun... and push of a button back to SILENT.

How do you like your paddle extensions? I was going to get a set for my A6, but was reading they don't help a lot.

As for exhaust, I'm leaning towards the rear delete and calling it a day. Those who complain about drone say it's in the 1,800-2k range. I've been watching my tach lately, and I don't think that range will be an issue for me.

[John_Kaufmann]

If you put it in manual and shift with the paddles you are good to go to pull the trigger!

love them, i can shift from any point

[StreetSatori]

Finally had a chance to get a video of my exhaust note this morning....43 degree F cold start no revs. ONLY rear muffler deleted with 3.5" tips as John stated earlier if you drive with paddles in dynamic the drone is very minimal almost non existent. LMK what you guys think??

Nice, I was reading that you still can't shift near the top of the extension. Good to know they work for you. Which ones did you get?

You'll hear it a bit but with my radio on at a "normal" volume I barely notice it after 3 full months with the delete...as John said nobody who rides with me thinks enough of it to mention it.

[coop3422]

As soon as this corona crap blows over, I'm getting this done. I'm trying to find an S6 diffuser so I can go with quad tips.

[Darknesssuper]

i currently have a test pipe to beckers downpipes to stock center mufflers to a set of a4 mufflers car sound great with out being annoying while driving normal if you would like to hear a sound clip check it out on my IG - ooogly_a6
i also have videos of the car with just a rear muffler delete also with muffler delete and test pipes ,and test pipe to becker downpipes to muffler delete

[24beastgav]

How would a front 2 resonator delete, suitcase replaced with non res x pipe, and quad tip conversion on an a6 sound? I have the x pipe where the suitcase is and it's not loud enough.

This is why I'm leaning towards deleting the rear mufflers instead of the suitcase.

[gkott78]

I should have my car back tomorrow, and I'll post a sound clip vid. I just removed the suitcase, but replaced it with 2 small mini mufflers. I had ECS cutouts put before the rear mufflers to bypass. The main reason for the mini mufflers was to attempt to reduce rasp when running the ECS cutouts open which is basically straight piped. I'm hoping it sounds as good as it does in my head.

[seemonkey10]

I’ve read all the threads and looked at a lot of options and think I finally found a solution that works for my ‘12 A7. I had the OEM mufflers removed and replaced with S7 sport mufflers, also replaced the center resonator with Magnaflow resonated x-pipe and quad 4 inch tips. It gives the car an OEM+ sound but a bit louder and deeper more defined tone with absolutely no drone on the highway and no rasp. It has also been girlfriend approved. We’ll see how it sounds after it breaks in but Im complete satisfied with the results
