Simple exhaust question
Currently I have OEM headers, no resonators, and a 330i ZHP muffler. Sounds good with very little rasp (being held in by the cats I presume). If I were to put on eBay headers which disregard the cats, would adding the second resonator to my current setup decrease the rasp? I know other ways to reduce it, but I want to know what you think about this setup.
awaits: hot cams, headers, tune
