Ok so I searched throught the first 7 pages and didnt find the answer I was looking for. What exhaust systems are you guys running on the S4 or what do you suggest. Obviously I am going to go around 3", but is there a certain brand or style that you prefer? Thanks

 

i heard an AWE tuning exhuast on there web site, sounds sick. But u already got an S4 so it already sounds nice.

 

Whats the sound level difference with a exhaust on S4s? I hope its not like my DSM. Sounds like a dump truck between the catback, downpipe and cams.
