Rotax Max Evo Exhaust named FFF

Rotax max evo exhaust named FFF

This exhaust is the very best we have seen from over 56 exhausts during a 2 year period. It is compared to Wright Engines dyno exhausts which is a proven stand out performer. Any of our exhausts which matches it, have gone onto race extremely well and even win races at the highest level in British, UKC and even BNL. 

see dyno sheet. Red= Dyno pipe, Blue = FFF
