Fist thing my exhaust is stock. I dont want it to be loud. And I dont really want headers. Just dont think I need them for what Im looking for. What I want to know is can I just remove the cats or do the aftermarket mids really help that much? Not really looking for the cheap way out. Just dont want to spend that much money if I dont have to. If I do get mids. Where can I get them for stock manifolds? Thanks for any info.
