05 best aftermarket exhaust

11 posts in this topic

Would like to hear some thoughts on aftermarket exhausts for the 05 YZ450.

With the detuning for 05 , I am real curious to see which silencers and head pipes help regain some of the hit.

I am real interested in the new Mega Bomb by FMF - does this header require the use of a FMF silencer and mid pipe or will the stock silencer work.

Thanks

this will cause many an argument - mine is better than yours.....etc.....

FMF is good, WhiteBros is good, procircuit is good - how much do you want to spend?

then there is the no names that so many love - Jemco, CHM, thunderalley,,,

BIG GUN , added a little more bottom end and rev on the top.

The 05 was not detuned, it lost no power, the power was spread over a wider RPM range to make it smoother = faster.

I put the Dr. D slip-on on my 05 450 and noticed an increase in the low and mid portion of the powerband. Awesome exhaust , it isn't too loud, comes with a spark arrestor, and has the option for a quiet core insert plus it is a good price. This exhaust was designed by the man who knows yamaha four stokes best. Matt
