All this muffler talk latley has got me looking into new exhaust. Has anyone heard the Moroso spiral flow system? Look good, I just don't care for the sound of anything with packing material for sound deadening.

That style muffler ( auger style ) has been around for decades... when the patent ran out several years ago some people knocked it off... Honestly there really are better mufflers out there than those. They dont move as much air as some of the others.
