B6/B7-S4/RS4 Exhaust Thread

I decided to start this thread for new comers with questions on which exhaust (cat-back) setup to purchase. This will hopefully prevent numerous threads on the same topic. When you reply please use the following format for easy information gathering. Feel free to post your reviews on the exhaust and reasoning why you purchased said exhaust.

Brand Make: Fast Intentions
Resonatation: Non-Resonated
Exhaust Diameter: 2.5"
Mid-Section Type: X-Pipe
Transmission Type: 6-Speed



Should be getting my setup within a few weeks. I will write a short review of it once it is on the car.

If your exhaust is not listed above please let me know and i will add a category for it.

[beemercer]

Here is my current setup

Catback:
Brand Make: Milltek
Resonatation: Non-Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: H-Pipe

Downpipes:
Brand Make: Milltek
Pre Cats: Gutted
Main Cats: N/A
Exhaust Diameter: 2.5"


Once I get some parts in I'll be transitioning to this setup:

Catback:
Brand Make: Custom Piping - Milltek Mufflers
Resonatation: Non-Resonated
Exhaust Diameter: 2.5"
Mid-Section Type: VAST designed X-Pipe

Downpipes:
Brand Make: Milltek
Pre Cats: Gutted
Main Cats: N/A
Exhaust Diameter: 2.5"
Other: Electronic Cutouts

Once my exhaust is all setup I'll post a full review on the sound and performance gain (2.5" vs. 2.25").

And great thread Joey, I can't remember how many times I have said "get a 2.5" x-pipe catback..." on AZ.

[Boosteda4tq]

Here is my Current Setup:

Catback:
Brand Make: Milltek
Resonatation: Non-Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: H-Pipe

Downpipes:
Brand Make: OEM
Pre Cats: Gutted
Main Cats: Gutted
Exhaust Diameter: 2.175"

The Milltek was on the S4 when I purchased it and the Gutted Dp's Where purchased from Joey.
It sounds good, its a conservative sound in my opinion and you dont get to much drone in the interior only on RPMs below 2500 anything after that the noise in the cabin gets less and less.

Here's my exhaust

Brand Make: Fast Intentions catback and downpipes
Resonatation: 14" Resonator with cats
Exhaust Diameter: 2.5"
Mid-Section Type: X-Pipe

[GameBreaker]

Brand Make: Fast Intentions
Resonatation: 8" Resonated
Exhaust Diameter: 2.5"
Mid-Section Type: X-Pipe

I love the exhaust, but to me it's still a little quiet. I have a tip, and do mostly city driving, but don't mind the drone at all.

I went resonated because I'm not a huge fan of raspy exhausts.. maybe a bad experience with the angry bees of an old M3. I'm still debating whether to go for headers or downpipes, but if I do go headers I will probably remove the resonators.

[DucatiR930]

Catback:
Brand Make: Milltek
Resonatation: Non-Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: H-Pipe


Bought the car with the Milltek Non-Res and I don't really have any complaints. It does drone a little bit just under 2K but I started to like the drone after a week or two. Piggie pipes are soon to come. I'm going to wait a few more weeks until it warms up a little bit around here.

___ with my B6 body ___
APR cat-back
Brand Make: APR
Resonatation: Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: X-pipe

This was my first exhaust on the car, the APR really changed the tune of the car; it made it sound more "euro" than "v8". Louder, but still quiet. No drone.


APR downpipes + APR catback
Brand Make: APR
Resonatation: Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: X-pipe

Wanting to make the APR cat-back a little louder I added 2.25" downpipes. I noticed an increase of sound; still not obnoxious, but not quiet either. There was a noticeable increase through the powerband.


APR downpipes + Milltek resonated exhaust
Brand Make: APR, Milltek
Resonatation: Resonated
Exhaust Diameter: 2.25"
Mid-Section Type: H-pipe

Wanting larger tips, I added a Milltek resonated exhaust. Milltek construction is a piece of shit. The welds are meh, and the hardware they supply is garbage. They actually include a tube of exhaust paste. FAIL. That being said, the resonated exhaust + APR DPs sounded sounded nice, but was actually quieter than the full APR setup.


APR downpipes + Milltek non-resonated exhaust
Brand Make: APR, Milltek
Resonatation: non resonated
Exhaust Diameter: 2.25"
Mid-Section Type: X-pipe

Removing the resonators really woke the car up; hands down, one of the best sounding exhausts EVER.

JHM longtube headers + GMG midsection + Labree mufflers

OMG WTF.



JHM longtube headers + STaSIS cat-back
Brand Make: JHM, STaSIS
Resonatation: non-resonated
Exhaust Diameter: 2.5"
Mid-Section Type: X-pipe

As well as downpipes:

Sounds absolutely amazing. Every car guy that hears it compliments me on it. But yea, its pretty loud when your pushing it. Not bad at idle, but under any load you hear it. It is loud in the cabin under load from 1500rpm to 2500rpm.

I had my connection points redone with flanges instead of slip-in style. As for sound i love it not too quite not too loud, no drone on highway.

Catback:
Brand Make: Corsa
Resonatation: Non-resonated
Exhaust Diameter: 2.5"

Downpipes:

I'm very satisfied with the Corsa. Great sound, great quality. The exhaust tips could look a bit better, but I'm just being picky.

05.5 B7 S4 6MT
Catback:
Brand Make: Fast Intentions
Resonatation:8" Resonated
Exhaust Diameter: 2.5"
Mid-Section Type: X-Pipe

Downpipes:
Brand Make:Fast Intentions
Pre Cats: none
Main Cats: yes
Exhaust Diameter: 2.5"

I bought the system used for $1200 and couldn't be happier. I needed something that wasn't too loud because of the area I live in and where I work. Most people don't even notice it unless I wind it up past 3k and then it definitely draws attention. The sound is deep and even a slight throttle blip sets off car alarms in parking garages. Under normal driving conditions, 25% throttle or less and it's very quiet. WOT its loud as hell! The perfect setup for my daily driver.

My only complaint would be how far the tips stick out past the bumper. Part of that is probably how it was installed though. I'm going to have them changed out to something a little shorter.

Usually not too loud, but around 2100 RPMs it gets louder when I let off the gas. Also at low RPMs it's louder. At cruising speeds it's pretty quiet.

I have messed with my exhaust set-up many many times and this is the best setup i have came up with. No drone and not very loud in cabin, but it screams when on it.
I will be switching to a b7 fast intentions b7 x pipe 8" res catback and 2.5 downpipes(custom)

[MOFSTEEL]

It seems like the Corsa system isn't very popular. Are there any known issues or are the other systems just superior?

Corsa was late on the scene compared to the more popular exhaust systems.
Many people had already chosen an exhaust and they persuaded future s4 owners to chose the same.

Personally I liked the Corsa tips the best as they look OEM.

Here are two short videos I took.

As you can see, just adding the Magnaflows made a big diff. DP's would have been best for both the sound and better performance, but this was a good compromise for a little while. I'll be doing piggies some day. Then she should sound really good.

lmao @ the birds

what model magnaflows did you use? i think i'm going to leave the exhaust stock for now and throw some mufflers on and then do piggies/exhaust all at once later this summer.

Most members choose the Magnaflow 14851's. You can pick a pair of these up anywhere from $200-300. Sure an install wouldn't be more then an hour of shop time or $100.

See video with just stock exhaust but added the 14851's on a B6.
