i was told by the exhaust shop that the resonator i use is basically a magnaflow, i should measure it. my old muffler was a 40 series flowmaster, and that setup droned so much more then this muffler dumped under the bed.
believe it or not, i fixed the majority of the drone i got from having the exhaust chopped off. got a rice pipe from pepboys, and its outer diameter is 4.5"
thanks, hopefully in a month or so, this new job is keeping me busy, so i should get payed more in hours alone, not to mention the $5 an hour higher pay
