i have headers and a high flow cat. sounds great. except for the drone. gets annoying wen talkin to someone who hasn't been in ur car before. but hey cars arent for talking. there for driving and blasting music. if u want to talk text me chief lol. but yea im thinking about puttin a glasspack on mine and fixing the 3 inch to 2.5 inch difference in pipe width that i encountered during my header instal so right now theres a little leak.
