im looking for a part number of the muffler in the mufflex kit maybe only non-polished for it to be cheaper. they quoted me 75 to ship to canada which is insane, so im just going to pick up aq muffler and get my local shop to weld it and throw a nice tip on the end. anyone find out with muffler they have used yet? thanks in advance. also is the single exhaust all 3in piping? muffler is 3 in and 3 out im assuming?
