- How to get a twin turbo V8 to sound good? Well that’s a challenge especially with a luxury sedan like the C7.5 Audi S6. If you want to improve your S6 Audi exhaust sound you need to brace yourself for a hefty price tag, but the real question is, should you buy a Milltek Sport Exhaust system?

The problem with turbo V8’s
Listening to this car in its stock form, it’s very subdued. The 4.0 litre V8 is almost hiding under the hood, buried beneath the turbos. It’s such a shame because it really can sound like a total beast!
After he bought the car, he and I went for a ride and both of us were like, cool, V8, but you can barely hear it. Granted this car is design to be comfortable with minimal road noise. But, if you are an enthusiast and you’re buying V8, you want to hear it.
So, going with a company that has high quality standards and equipment to fabricate this exhaust was a good place to start. We did try AWE Tuning, which is the North American counterpart to Milltek Sport, but they didn’t offer a valved system.
Another thing, all Milltek Sport products are 304L, or aircraft grade stainless steel. This means that for wear and tear, especially rust, you are getting a system that will last.
Installing the full exhaust system
With a few bolts and hangers removed, it’s actually quite simple to remove the entire stock system. You could do at home, but it’s always nicer in a shop with extra hands. The Milltek Sport system install is done in stages, first the headers, then center H-pipe with provided clamps, the rear muffler.
So what do you get with the Milltek Sport Exhaust Valved & non-resonated cat back system? In the box;
LH FRONT PIPE ASSEMBLY
RH FRONT PIPE ASSEMBLY
CENTRE SILENCER DELETE H PIPE
2 mufflers with valve controls
4 finished tips
Valved mufflers vs non-valved
So let’s talk about the valved system, they do cost more so here’s why I think you need them. Some Audi’s, like my RS5 and his S6, give you the option from factory, to equip valves which can be manually opened and closed. This lets you control if the exhaust note is louder and quieter.
Unlike my RS5, the Audi S6 has a fuel economy function which at certain cruising speeds, it will deactivate half of the cylinders. While this can be more fuel efficient, it sounds terrible.
Keep in mind, you are going to need 1 wiring harness extension. This is something we didn’t realize until after we ordered the system, so he drove around the first week with only a half valve open. So, remember, wiring harness extension, they’re about $25
H-pipe vs X-pipe
Next up is the resonator section or center muffler. Again, because we are going for sound, don’t waste money, the center resonator removal is going to give you a lot of volume so either get an H-pipe or an X-pipe.
We debated back and forth on this for a while. From what we could tell online, the X pipe was the way to go for the S6. The problem was finding a system that was configured this way. Our idea was, order the Milltek Sport valved, non-resonated, cat back exhaust system in full (which comes with an H-pipe), then separately, order an APR X-pipe and install it after.
So how does the Milltek Sport Exhaust system sound?
Ok, wow. Where to begin on this. For starters, it doesn’t even sound like the same car anymore, especially on cold starts haha. The H-pipe is quite perfect for the character of the S6. There is a lot of low-end rumble and it sounds angry as hell. The overrun, or pops and crackles, are hilariously addicting.
Whistle sound from exhaust
Drawbacks? Well, you might notice a faint whistle at idle or low rpm’s, we thought that might be a valve half closed, or maybe the waste gate from the turbos. Either way, you don’t notice it while driving and it’s very faint so not a problem.
Milltek Sport Exhaust Price
Yes, at nearly $4,300 it’s a hit on the wallet but bottom line, there aren’t a lot V8 sedans like this anymore, and if you are fortunate enough to get your hands on the C7 or C7.5 S6, the Milltek Sport Exhaust is a great way to open it up. - Авто та транспорт
I got the same exhaust, 200% recommend
Thanks for the feedback, and thank you for watching 👍
Almost bought an S6 a week ago. Badass cars with a lot of tuning capability! Went with the RS5 B8.5 instead. Was a hard choice.
Thank you for the feedback. Definitely, the S6 is very practical, great daily driver, and you get that twin turbo V8! But, the rs5, that 8,250 rpm redline…hard to beat. Thanks for watching 👍
@@WhyBuy thank you for the video! You and other channels helped influence my decision.
realy you chose the 4.2 v8 over the 4.0 TT v8?!?? why?!?!?
@@darrinscoilsclouds1498he made a bad choice ?
@@LJMcCrayUofF 4.2 is there older technolagy and hs more "audi gremlins"
Well made video 👍
Thank you for the feedback! and thank you for watching 👍
Great video fellow cowtowner! Looks like you got your rs5 the same time I picked up my wife’s sq5. Both CJP plates lol
Haha small world and thanks for the feedback!
I've got a 2018 S6, I did just mid pancake resonator delete and removed the valve in the exhaust. It sounds a lot better than this. Have to say, you can make it sound great for not a lot of money.
Lol so loud. I'm going resonated because I care about my neighbors and I want more relaxation on daily drives, but this sure looks fun.
Thanks for the feedback! If you can, keep the valved system in the mufflers, you won't have to worry about loudness and your neighbour's. Thanks for watching 👍
@@WhyBuy Thanks for the tip!
Great video. The S6 might be the next car on my radar. Just have to figure out if I really want to let go of my RS4 or not.
Tough choice, both are great cars and have their own unique qualities. As a daily driver the S6 makes more sense, but for a more special drivers car, the RS4 hands down. Thank you for the feedback, and thanks for watching 👍
Incredibly helpful video! I'm gonna go AWE. My plans are to tune it using Intergrated Engineering, cold air intake through them as well along with the AWE exhaust.
Thank you for the feedback, and that sounds awesome! Btw, watch your transmission (with any tune), the increased HP and torque might but additional strain that MIGHT cause issues. Best of luck, and thanks for watching 👍
How did your build turn out? I also went with an AWE touring exhaust and will have the IE intake in a few weeks.
@@matthewk4497let me know what the intake does for you. I’m on I.E. stage 1 E85…looking to do stage 2 but I.E. claims it doesn’t make any more power?
@@matthewk4497 question for you... Does your exhaust set up with the AWE touch your OEM cats/downpipes?
*crosses off A6 3.0
*adds S6 4.0
Haha
I'm glad I came across this video cause I'm looking into buying a S6 so I can get these pipes..what year & model is this one
Thanks for the feedback, this is a 2017 C7.5 S6. Thanks for watching 👍
hey bro im a fan from china. i was really into RS5 after seeing your vid, but my pal brought one and the mugen V8 engine seems not really my favorite sound. i end up buying a sepang blue 2016 S6 last week, after seeing Dallin Sellers vid about his AWE straight pipe S6, the sound was really lika a proper American muscle car. but mine came with Akra exhaust, which i find the sound too subtle for a younster. after seeing you vid im sure i need to get mine milltek hahaha. Love your channel, btw r u going to install downpipe ? will get bigger maybe better sound, please try like 200 or 300 cell downpipe (dont straight pipe it). lets see the outcome haha .
Thanks for the feedback, and that's great to hear you enjoy our videos. The Audi 4.2 in this B8.5 is something special, not sure if it is actually a Mugen V8, although I have heard rumours that it may been derived form their race car, which might have borrowed design elements from the Mugen 🤷♂️ who knows. Nonetheless, congrats on the sepang blue S6! The cars sound great, easy to live with, and there's no desire to get more volume from the engines (for now haha)
Thanks for watching 👍
@@WhyBuy this is the akra cold start with 200 cell downpipes ~
Identical spec to mine. I kept the rear stock mufflers and went to a catless down pipe and rez delete X pipe. The sound it's nasty with pops and bangs with no annoying whistles lol
Thanks for the feedback, we were wondering if the whistle sound would be eliminated with an x-pipe. Still might swap out the H-pipe but that uneven airflow does give it that nice rumble and tone. Either way, than you for sharing that and thanks for watching 👍
@@WhyBuy forsure that's the downside of the H-pipe. X-pipe eliminates that weird low end turbo noise.
Switch out to x pipe
Beautiful car, great video, great exhaust system but the H pipe doesn't suit it. It's a European performance V8 - not an old American muscle car. Sounds gaspy . I'd be swapping to the X pipe for sure.
Hey. Id really love to hear the s6 with the x pipe. I think it would more of an Australian/euro sound to it. Smooth and throaty
Still haven't swapped it in, but if we do you can expect a video to come. Definitely agree that the x pipe would change the characteristics of the v8 sound, tempting, but not an easy swap. Stay tuned and thanks for watching 👍
I will choose Capristo
True, but $$$
is this sold>?
i sold my Q50S 3.7 with the best V6 sound at this price range, now im heading for V8 before EV dominate our life... haha
The days are counting down thats for sure 😢 if you can, now is the time to enjoy the beautiful V8 sound, still so many good options around this era, good luck!
Thanks for watching 👍
Did feel like gain more hp?
There might be a slight horsepower gain with the less restricted airflow but without doing high flow headers, you wouldn't really see any change. The sound is what you want, a V8 with better sound +5hp 😜
Removed from the cats and not the headers as repeatedly stated.
Good catch, and yes that's absolutely right. This is a cat back system so not including headers. Sorry for the confusion and thanks for watching and providing feedback 👍
that squeeking sounds horible. its a must fix in my book
RS5 sounds better imo. If he swaps out the h for x pipe then it’ll good
The difference is pretty noticeable between the Xpipe and the Hpipe. However, in person, the Hpipe does have a deeper rumble and you sort of "feel it" more when standing near it. The camera doesn't quite capture that, but I agree nonetheless, the X-pipe is a more refined sound overall.
Thanks for watching 👍
@@WhyBuy sounds good thanks 👍🏾
rs5 sounds better but s6 is faster. both are unique in their own way
Very true, apples and oranges. Thanks for watching 👍
