how loud is the cobra exhaust compared to the HMF and how much is the increase in peformance compared to the HMF

I have the cobra on my bike, and its is well worth it for the money. I paid around $160.00 or so for mine. It really helped the bike out. It is louder than stock, but not unbearable by any means.

IMO the cobra pipe is somewhere between the stock and HMF pipes, noise level and performance wise. It is an old school pipe and it has been around for along time. For the price you can't go wrong, anything above stock is a improvement. But for max performance HMF is the way to go.
