straight throughs sound cack, imo, loud too raspy and alwyas sounds like your ragging it even when pulling away slowly.
my de-cated ahsley is the bomb, proepr competition setup, no girly tailpipe etc. jsut faces down like a diesel but it sounds amazing. even on idle, its quiet but you han hear the air pounding down the pipe, sounds like an old carbed engine exhaust, if you know what i mean.
