Hey guys I am abou to buy a 2005 GSXR-750 with a micron high mount slip-on. Not a big fan of micon or the high mounts, plus my buddy has one on his R1 and doesn't sound that great to me. I came up with an idea to see if I can modify a new M4 GP Slip-on, man after seeing this pipe and listening to it! Man! it sounds good, i have heard from another to buy a 05 1000 header and then the slip-on but I was just hoping to maybe get lucky that both the slip-on diameter is the same as the stock headers that are on the 750 now. Tell me what you think.
