I have an 2.5" inlet N1 sort of muffler ( no markings on it ) its very flow happy. Inside is gutted of material no wool or perforations ( maybe it came that way idk ). Looking for something new before hitting the muffler shop, possibly a chambered type muffler... vibrant, magnaflow, dynomax, rsx, 06+ si? Send me offers whatever it is
