Jim,


What did it gain on the dyno?? Can you email charts? Why is it being sold??

Off the top of my head, my friends Busa in stock form pulled 156 rear wheel on a Dynojet 150. With just adding the M4 it increased to 163. After opening up the airbox and using the Yosh tuning tool it pulled 168 and change. I should be able to get dynochart printouts over the weekend and have them scanned for email by Monday sometime. He's selling it since he's having a custom titanium dual silencer system made for his bike and it's almost complete.

Please email me and send a weblink or photo. I have a friend that just bought a new 2000 and is looking for a pipe.

All tests were done on a Dynojet 150.
