New FMF Pipe?!?

Recommended Posts

Thats a crazy looking pipe but I think its impossible for a header to gain 3hp over the old PB especcialy on a 250.

"Partridge’s mechanic said his RM-Z250’s expansion chamber on the header pipe puts out 3.5 hp more than the standard pipe, and it’s 2 db quieter."

Looks like it does add at least 3hp.
