So I sold my '07 YFZ450 this weekend and now have a '08 YZ450f. I was bored and wanted to get back to 2 wheels. My question is what is the way to go with exhaust on one of these bad boys. Slip on? Full? HMF FMF Dr D I mean its so hard to tell. Hoping some of the guys out there that actually own one can give me some input.
