Exhaust systems

[logan_450R]

I am looking to be getting a full system for my 06 YFZ450 and its between the Big Gun Evo R or the HMF sport series . Which one puts out more power and in what areas do they give it at and also which one is louder?

[yfz450les]

i would recommend the hmf sport series gives mid to topend power and revs alot better on bottom & i dont kno how much louder but sounds 100% better than big gun

[yfz stealer]

man forget both of those and get the Rossier best pipe i ever had

[logan_450R]

what kind of power does the rossier throw out

[hellbound250r]

it gives you good gains all over. decent bottom, strong mid and good top. all around good pipe. i love mine.
