Wanted to develop a high torque low rpm pipe that would work great with my clutch kits or other clutch systems.

Trying to get the exh pipe to make the engine turn around 8200 rpms. Not sure on the hp increase that will happen. The test engine is a brand spankin new 2003 800 except Dalyn had Chad replace the pistons with wiseco. The wiseco have improved transfer port relieve to make the engine flow a bit better.
