New 2010 HMF Competition series exhaust on my bike. I have an aftermarket fmf header on my rmz so it took a couple hours to get the 2 pipes to fit together but once i got it on i was impressed. The HMF pipe looks amazing and sounds soo much better. Idling it's a little louder but not that noticeable. but when riding (and especially in the high rmp's) its super loud.
I haven't jetted it yet, but even without jetting it i can feel a nice low-mid range performance increase. Definitely brings the front end of the bike up easier!
