there are 3 type of muffler, straight through (fart can), chambered (stock, rsr ex-mag and stuff)
down side of straight through is beiong louddown side of chambered is power robbed from being chambered
this twin loop design solves this problem however, looks funny and usually hard to mount properly, usually require more clearance to fit properly
