This muffler design is a straight pipe thru. It's based on Dynomax's ultra Flo welded mufflers. They out flow almost all street mufflers while being the quietest so far. I just want it to be light in weight. Yes, I do need to be quiet for many reasons but need some what of a loud enough note mainly to wake up all the Hipsters staring down at their I-phones while walking against the light on the crosswalks as well as my own sanity.LOL. I've never used the horns on my car because of its presence known two blocks away coming. Semi-loud pipes saves lives like no other these days.
