Does any one know where to buy a cheap 2.75-3” straight pipe cat back exhaust, no mufflers just piping for a 16 5.7? I can find systems for older models and the v6 for $200, but i can never find anything for the v8 especially over 2.5”. So far did mid muff and res delete with slp res thrown in but car sounds like it wants to burble and pop but cant bc piping is too small. Anything else out there besides muffler systems over $700?!?
