i had just the slip on. it made a noticable difference i thought:)

I have had the Pro Circuit for two years now. Nice pipe. Don't expect a big jump in top end power. Mostly mid range improvement. Try jumping to a 155 main jet and go from there with a stock air filter.

I got it with a Powerbomb head pipe. Good pipe I am sure you will like it. :D
