I'm thinking quads oke:1slosix said:when i bought my current sixxer it had a canister muffler on it..not gonna lie it doesn't sound bad. if it had looked better under the bumper i would of probably run dual canisters.
to be honest they are built about the same as an m80, or borla canister muffler. i still have this thing in my garage..i might buy another one. and put them both on the car if it sounds good i'll slot the rear bumper to house the tips better and run them
