Just like to start by saying my bike is a shadow spirit 750. I have the stock exhaust with a holesaw mod, and would like to completely gut the exhaust and put a stage 1 jet kit in the bike. Has anybody done this before? I'm thinking I could just take a 2 inch hole saw with a 12 inch extension and cut the baffle out, but i'm not sure. I dont want to just keep cutting assuming it will come out, and end up cutting through the front of the pipe. I guess i'm asking, does anybody really know how the inner baffle is in there? And also, has anybody gutted this exhaust that knows what i'll be dealing with?
