Dunno if this is the right section... i think it would be. But i have on my exhaust, 4-2-1 header, oem cat, resonator, then muffler. I'm going to need a baffle in there because when i put my fart cannon on with just the stock header, OEM cat, resonator fart cannon, it was way too loud. now with the 4-2-1 its going to just get louder right? IM thinkin of going to the wrecker and finding myself a resonator, just cut one off and weld it on my setup.. will this tone it down much? or should i just look for a new cat? I know the cat on there right now, it rusted to hell, and the shield is gone on it, and i think it might be causing it to run rich,.. new cat, or att a resonator? what you guys think...?
