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.

Don, I'm emailing you the dyno charts comparing dead stock, M4 pipe with Yosh ECU tweaking and M4 pipe with Yosh ECU tuning and gutted airbox (all stock stacks). Here's a summary of the results...

Stock.............156.8hp/97.5 torque
M4................162.6hp/98.7 torque
M4w/airbox mods...166.9hp/101.4 torque

All tests were done on a Dynojet 150.
