It's also the worst flowing aftermaket muffler out there... creates alot of unwanted backpressure...
they are tough as nails tho....


stats ? .. as far as I know , they are a free flowing /minimal back pressure muffler .. it's what I have read anyway . only down issues I have read and heard on wave files .. is there loud .. but' i'm likin' the noise ..
