Go with the HMF sport series full system. I bought one and was definately impressed with sound and power gains. I don't think that you will be disapointed. Not to mention the folks at HMF are awesome, very good customer service, they stand behind their products and make sure their customers are satisfied.

I would with out any hesitation go with the HMF full system

I've got the HMF full and it rocks, but if there would be a difference in power it would be minimul. You've already invested in a pipe so now go for something else like a cam.

I would go with the HMF. I can't remember the jetting for a stock motor but if you call HMF (866-463-7473) they can give you great service.

I had to go one size bigger then they recomended. Just be sure to check your plugs after you rejet it.
