exhaust ?s
right now my car has a flowmaster muffler on it. the guy just chopped off the old one and welded the new muff on.
what's the proper procedure here? i need a high-flow cat-con? what diameter piping? what's the deal with dual exhaust? i'm totally a noob.
also pricing if you remember how much it cost when you got yours done.
thnx
mike
