Exhaust inquiry....
In the classifieds someone is selling an S4 exhaust with the "pre-cats" removed. Here is the question, what are precats? I understand that the cats restrict the exhaust but we cant get away without them for emmissions, correct? Still learning so much about my baby every day from you guys, thanks!
