05 450r. I haven't seen many posts on the Bill Ballance pipe setup and am considering this kit or the HRC kit with a Rossier.
What do the experts think?

Thats my exact setup as of right now, with the Hotcam stage 2. If i were you that's the one i would get because it gives more of an increase in power over the entire power curve. Look at hotcams website and see the dyno charts. You will notice a big boost in power, way different from a stock bike. The pipe choice is up to you, the Bill Ballance exhaust has a TRM insert that smooths out the power delivery noticeably. IMO i dont really like having the insert in there, so i took mine out. It makes the power come on more peaky it seems like. Overall this is a good setup, but if you can find a cheaper exhaust it might be easier on your wallet. I kinda wish i had gotten a cheaper one.

That looks like a really great setup. What do you think the pros and cons between this and the HRC kit are?
