Exhaust options for 23' RS3?

[FIGUY]

Newbie to the forum and soon to be first time Audi owner as well. I lost patience waiting for an RS3 allocation exactly how I wanted one spec'd out, so I caved and accepted a similar build (Turbo Blue) as part of a block allocation. Car is due in a few weeks, and I am beyond excited but the one option I am missing out on is the sport exhaust. I have seen many reviews where the driver complains that even with the sport exhaust the car is too quiet, so maybe I am not going to be missing out on much. Are there any aftermarket options for a cat-back exhaust system yet other than the Akrapovic titanium?

Thanks!
Jeff

There's a few, but im torn on waiting for AWE Tuning or Boostlogic to make one, or going with one of the German brands that have already made them. Here are the ones I've found so far that are available:

I believe Supersprint and Milltek offers a exhaust for the 8Y platform according to their website. Boost Logic will eventually be offering a titanium exhaust for this platform as well.

I think I'm going to shoot for this one next year -

Provocateur Exhaust - revving / driving start at 5 minutes / bumper mic bits are at 7:50 and are

Also - Sport exhaust is lame from the factory - It's definitely waaaay too quiet for this car. I'll keep it to the side but will be getting something else.

I've seen a few posts about the ASR valve controller. It's pretty surprising how much a valve controller actually changes the exhaust...

[grandpab]

Also, from what I've seen the only difference between the sport exhaust and the standard exhaust is the size of the resonator in the midpipes. The sport exhaust is a few inches shorter. A sport exhaust and the standard exhaust both with the resonator delete midpipes would be the same setup.

The midpipes remove the secondary catalytic converters on the 8V platform and the exhaust setup looks nearly identical on the 8Y.

Why don't you just do mid pipes first and then see if you're still in need of an exhaust change?

This is going to be my daily driver, so I would rather keep it smelling nice and not have to deal with emissions issues on an annual basis come inspection time. My weekend toys are exempt from emissions and are all straight piped though

[FIGUY]

Thanks for the list of options. That is great news that Boostlogic is going to be making an exhaust, as I am very familiar with them from the Supra world. Have they shared an eta?

No problem! Last I spoke to them (a month ago) they will make one eventually but they dont have an 8Y on hand and I dont think they even have one on order. They said they are down a fabricator and have other important projects they need to tackle first. So it might be a while. I offered to send them my car for a couple months but I ended up changing my mind haha. I know how shops are on R&D cars and it would worry me being there for that long.

Unless something has changed in the 8Y, there's no post mid-pipe emissions sensors. Many ROW cars don't have this secondary cat and you can buy the Audi OEM mid-pipe to delete them. Also, many aftermarket exhausts are going to eliminate it as well.

Zero smell with the secondaries gone on my buddy's car. There is a still a huge primary cat.

You won’t smell anything from going catless mids and it will improve the sound a bit. I did this with my TTRS.

Agree. I have catless mids on my 19 RS3. Comfort mode / valves closed essentially unchanged as well so still 100% neighborhood friendly.

[tateltot]

Definitely +1 to all the comments about the mid pipes. Start there. It's a very inexpensive mod with a huge difference in sound. No smell, by the way. You would need to swap the mids back in for eventual emissions inspection (in some places), but it's a very quick process.

[FIGUY]

Will a car pass emissions without the mids, if no visual inspection is done (car isn't put on a lift)?

[tegxsi]

Depends on your area...
Mid pipes will pass OBD readiness since the secondary o2 is only checking the primary cat.

[mtwallace85]

I don’t think they’ll fail unless it’s a visual. That being said, these can be swapped in about an hour. Not the worst thing ever to have to change them back for the day.

[nimri09]

Just spoke to AWE, estimated November launch for their exhaust system for the 8Y. They have theirs in development already. Gonna get their affordable track exhaust when it releases and call it a day. LFG

[k33psp00lin]

Which mid pipes does everyone recommend? Is it confirmed the previous gen fit the 8Y?

I've heard CTS fits.

[mtwallace85]

For the 8v RS3/8s TTRS they’re literally all essentially the same thing. Just go with the cheapest option and call it a day. You can even order an OEM set for about the same price as the aftermarket options.

I was referring to my 8Y, is it confirmed the 8v options all fit the 8Y?

[k33psp00lin]

Thanks, I will probably go ahead and order from CTS since they advertise fitment on the 8Y!

[Vegasgolds]

Unitronic mid pipes will fit the 8Y

Great, thanks for the recommendation.

If it’s like the 8V version, it will be obnoxiously loud. It’s basically a straight pipe exhaust from what I recall

[nimri09]

It's not my daily so I'm totally okay with that. At least if and until something better comes along. Right now I can barely hear the damn car

Are you going to try the mid pipe swap out? Just curious - Houston here I'd be interested hearing in person if you are lol. Car is super quiet even with 'sport' exhaust.

Not yet, dont want to give the dealer any excuses to void my warranty. Im already having a couple issues with the car and having them try to figure it out. I know for a fact catback and intake wont void, thats all ill do for now until im comfortable without warranty lol. Yeah im in houston, down to meetup whenever!

Sorry to hear all solid here thankfully, and I plan to not use the dealership as much as possible and have quickjacks for my oil changes and such as well. Good luck with your issue though - I'm going back and forth on the midpipe myself - honestly it's so minor it could be swapped in and out if needed to take to the dealership. If you wanted to swap it I'd be down to help.

removing mid pipes will NOT void your warranty. It's NOT a performance mod

[noseyp]

OEM catless midpipes for 8V are standard in Europe due to OPF filter (links below). I acknowledge that they are listed as discontinued but some folks bought them and one had the dealer install. Most catback systems will replace the midpipes with their version of the catless ones. I have uni midpipes and have done service at the dealer with them installed. No issues.

Maybe I'm dense, so please help me out. But do US spec cars have secondary cats built into the mid-pipes? The Unitronic mid-pipe page only mentions deleting the resonators. I'm curious because I plan to run my car in SCCA autocross in BS class where I'm not allowed to delete cats but can change the exhaust downstream.

Yes the midpipes from the factory have secondary cats built into them. Most people swap these out because its quick and doesn't trigger a check engine light.

The catback wont void your warranty but the midpipes will? How did you come up with that?

[noseyp]

Some good information on midpipes in this old thread.

Never said it will void warranty, just said I want to play it safe as catback is the only thing ive personally confirmed so far with the dealers in my area that doesnt void warranty, so I'm playing it safe for now.
