Pro-Circuit shorty

[Florida400EX]

Hey, I'm interested in a Pro circuit that was shortened 4 inches. It's the one crap-banshee is selling. I wanted to know if it would fit my stock headpipe? How much performance will I gain on a stock motor? How does it compare to HMF?
thanks!

i know on a stock motor. with a filter and a rejet you will get a load of tourque and with the 4" off it will be really loud. not to sure if a hmf is better or not

I run a shortened T-4 on my 416 and am pretty happy with it. It really isn't that loud compared to an HMF. I really didn't notice a difference when I cut mine down. (mine had a dent in it and the rivets had loosened up) T-4's are a pretty nice slip on in my opinion. It will work on your stock head pipe also.
