Tell me which one you like better because I can't decide. I like the way both of them sound and they both have good gains but I can't decide.

both are nice pipes. just get the full systems either way. the sparks with its reverse megaphone design will pull a little more high rpm power. the hmf probably has a little more low end power though. we have had good luck with both pipes.

If you put the X-6 on your bike it will give you more top end. If your looking for more off the bottom, then go for the Curtis Sparks
X-4.
