Just wondering what muffler you guys were using to quiet these systems. My aftermarket has one large canister magnaflow muffler (not sure of design). There is alot of caban noise as well as spitting and choking coming off rpms The outside sound isnt very loud. Was thinking either a good long glass pack or a screw design muffler. I will be running a race header in a couple of weeks and i think the sound would be unbarrable the way its setup right now. Suggestions?
