it wasent needed but everytime a hear one word about fmf there is always someone bashing it and saying it is sh*t
The only slight performance gain on a right bend pipe is the air cooling pattern. Friend on facebook had 3 blasters at once. One had an fmf (trail ridden), another had a Shearer, and the last one had an F7. He took the temperature on the one with shearer and F7. He read out only the F7 decreased the temp by only 3 degrees F.
