Couldn't decide whether this was a talk or a tech topic, anyway, curious if anyone knows a good source for Mac's full stainless catback for 96-04 GTs (Mac P/N TK8604). So far every page I've found that offers this systems has been in the $450 range, and eBay doesn't have the system at all. If anyone has a source for a good buy on this system, I would greatly appreciate a point in the right direction.
