As of now i am looking for a very loud exhaust for my s4. I hear that the labree cat back is loud. Any other opinions? Any loud custom jobs that sound good? thanks

 

I'm looking for the same thing. I wouldn't use the word loud, but all the soundclips I've listened to sound pretty close to the stock sound.

 

I ended out buying this setup It is VERY loud.

Let me know what you think..

 

i went with flowmaster super 10's on my b6 s4.... its alot throatier than any of the aftermarket catbacks i have heard. i have stock downpipes and just an x-pipe in place of my resignators....

total setup with install was 300$

i will take a soundclip when i have a chance and post a youtube url to it

 

I am also looking for suggestions for my B7 S4. I, however, want an exhaust that isn't overly loud, but gives good gains and quality. I was thinking about APR because there is a great shop in my area called Achtuning. Not sure though, any suggestions?

here is mine with the flowmaster super 10's.

kinda sorry video quality, but you get the point of the exhaust.

super quiet at idle but has a nice growl to it
