I was wondering if anyone has got the hrc kit and a full system hmf or curtis sparks. I have the hrc kit and am going to get a pipe soon and those are my top two so far. I would appreciate and feed back.

I should add that I have read alot about pipes and how they have done over stock but I have not heard much about a full system and a hrc kit and thats why I am asking. Just wondering if it is much of an improvment over the hrc kit. Thanks

Thanks I appreciate it. I talked with John from HMF and I guess he is one of there dyno guys. He said that they just put the 450r with the hrc kit on the dyno and that the hrc cam causes the 450r to loose alittle horepower in the bottom but that it puts alot of power on the top end. He said the hrc kit adds about 5hp and that there full system adds 7-8hp. He said that the power increase really did not take off intell about 6500rpm's. This is werd to me because I thought that It felt like it had more power down low.

But I could tell that he knew what he was talking about. I should add that he said that he took it for a ride out on there black top after the dyno and that when he hit the top end that it and I quote"that thing took off like it was shot out of a gun, it was like a rocket". I liked the sound of that.

scott at curtis sparks told me the same thing but that there full system was 5hp and hrc kit 5hp
