that sounds pretty complicated lol, and possibly not worth it? I don't want to create headaches for myself down the road. Lots of people recommend the Euro headers, but then probably wouldn't get the same sound here? No one's mentioned a Euro cat before.. both of those would still work with the SS X Pipe and exhaust?
