Hi there!
A question about head pipes of the exhaust system.
I had lot of power gain from a complete exhaust system instead of change only the mufflers.

Also on the big mono (LS650) of my girlfriend I took different gain from a complete custom handmade exhaust system with big diameter header pipe.
I want to ask if someone of you has found and bought a complete exhaust system of better stainless steel quality and larger diameter and optimized flow.
When I'll get my Bonny or Speedmaster the first mod I want to do is the building of a complete stainless steel natural finish and mirror polish exhaust system.
I'll try to optimize flow and use larger header pipes and an Harley style baffle into the mufflers.
