Re: “Quiet” performance mufflers
ive got a set of those im gonna try on my truck...
the only thing I see that looks odd is if you look into the muffler I have for 2-1/2" pipe it necks down to less than 2" on the inside...ive also got a set of dynamax knockoffs im gonna try...were gonna run both sets on the dyno and see if theres any diff..
