Audi S6 Stock Exhaust vs Milltek Non-Resonated H Pipe vs Milltek with APR X Pipe

Comparison between the 2017 Audi S6 Stock Sport Exhaust, to a Milltek Non-Resonated Exhaust without rear mufflers (straight pipe rear mufflers), to removing the Milltek H Pipe from the center section and replacing it with an APR X Pipe. SRM Long Tube Intakes Installed before X Pipe was placed, enjoy the turbo noises.
H Pipe Thoughts - audible at idle, loud cold start, more of a raw V8 sound, choppy exhaust note at lower RPMs, good amount of drone on the highway, few extra pops and crackles compared to the X pipe.
X Pipe Thoughs - much quieter idle, still loud enough on cold start, cleaner, more exotic, or more consistent exhaust note throughout the RPM range, tolerable amount of drone on highway, plenty of pops and crackles, it does not go away like some people say.

Xpipe is definitely the way to go

[@ahmedalyafi9652]

X pipe sounds waaaaaaay better. Less chopping noise. I can’t describe it better but sounds better lol

[@adamiscoo4]

There is substantially less drone with the X Pipe than with the H pipe, but there is still a small amount. Took a 2400 mile road trip and the drone was not tiring or annoying at all. The H pipe had a louder drone that resonated throughout the cabin

Great video, I'm looking to go aftermarket but use miltek design pipe sizes and H pipe to create a similar sound to them. The H seems more raspy and mustang like whilst the X is more subtle and deep. I plan to get straight pipes and H with valved back boxes so hopefully drone shouldn't be that bad, if it is then I'll maybe add some baby resonators

I think H pipe sounds way better on idle and low rpm i have IE xpipe and mid pipe going to stock exhaust and i hate how it sounds on idle . Im looking to remove the IE x pipe and install Miltek h pipe but i think 2.76 piping on miltek h pipe wont fit stock exhaust .

X Pipe Sounds 2 times better

What is the air intake system you are using? Seen at

Funny how your license plate was censored on the lift but not in the garage or driveway LOL

[@omichaelnato5388]

Love it, I recently drove a ‘12 R8 straight pipe, you think the S6 can achieve a similar sound ? Or another model ? (Maybe S8? Definitely RS7)

[@bbigrocker1]

In all honesty, there is NO COMPARISON

[@sinoperture]

Quickest way to cheapen a car is to make the DSG fart louder.... need a way to filter that out..

[@crispcarguru303]

X pipe definitely fixed the weird tractor tone it had.
