I want to get some more sound out of my S4 and need some opinions. I was looking at some electric cut outs, anyone used some? I would love a cat back but I'm used to my old Mustangs where you can get a SS cat back for $400 and I look for my S4 and I see $1,000+. Anything I could do got like $500 or less? I was thinking the cut outs because they're $360. Appreciate any input

 

Cut outs may give you a dash light but, I would go after cut outs if you just want sound.

 

The Millteck system sounds real nice. It is definitely worth the money. Look around on the various Audi forums , you might be able to pick one up used for the price your are looking for. If not dig deep & enjoy the sound.

 

Vibrant resonators, Magnaflow mufflers, and custom piping. Should be around $500-600 and will sound great. At the same time, you moved WAY uptown going to a B6 S4 from the mustang world. Most of the time you're gonna have to pay to play.
