I have a mac 4 to 1 and i drilled holes in the baffele to make it a little louder and it still sounds like crap. The guy i work for gave me a 4 to 2 slash drag exhaust from cobra i believe what would you guys prefer? my bike is a 1980 kz650 ltd. Does the 4 to 2 exhaust really louder than the 4 to 1 like everyone says? Hows the performance because i have k and n pod filters not the cheap ones either acutual k and n pods stage 3 jet kit and 120 main pilot jets in it?
On my SR650 I had an muffler with no baffle but with a homemade end cap to replace the baffle. It sounded pretty good it was Extremely LOUD though, as in a cop heard me over a mile away loud :laugh: :laugh: :laugh: :laugh: (and it is a kerker 4-1)
