Default Re: Expansion chamber header pipe angle question

The header length is very important!!
That factory motorcycle pipe you're using is already about the right length for proper tuning.
You'd really be better off cutting it and turning it to fit around the frame (& get the factory flange as close as possible to the engine exhaust port).
