So I found this kit on ebay and it looks to be a really good value, all I would need is the hmf slip on. I have not heard this combo but someone said earlier it sounds good. I really like the Dasa, it sounds great and and would look cool on my black bike. I originally was going with the FMF 4.1 Factory system w/ pb header but this site seems to believe the dasa, rossier, sparks, or hrc & hmf combo is best. I guess I am a push-over lol. What do you guys think?

It depends on what you are doing. Do you want most power available get a DASA, If not 1.5hp less get a HMF.

Either choice is ALOT better than FMF. I have the hmf/HRC set-up, and i like it. I went with that because i dont no how long i might have this bike(2010-new 450r, or other 450's??). But you cant really go wrong with it, it seems dasa only beats it up on top end.
