Is anyone out there currently running a HMF exhaust? I put a Supertrapp IDSX, re-jetted the carb w/K&N filter and noticed good gains. Recently rode with someone that had an HMF pipe and it was AWESOME. Thinking about going to the HMF full system for my grizzly. Any thoughts. Also, have an aftermarket hi-performance rectifier coming as well. My buddies on the Rincon's are hating it!
