I'm wanting to upgrade my exhaust system for my A4 Avant 3.0 . I was thinking of doing my own custom set-up threw a local exhaust shop since all the kits seem pretty outrageously priced. I was going to go with MagnaFlow mufflers but unsure on what to do for the rest of the system up to the headers. Anybody do there own system like this? Curious about the details and gains , sound , etc..

Thanks.
