07 Yz450F exhaust

is the new Pro Circuit T-4gp system a good exhaust for the 07 Yz450F?

if not, what ones are best for durability and performance?

thanks in advance.

Its hard to beat the Dr-D system for the price. Good overall performance, good durability. The pro-circuit is a god exhaust as well, just a few more dollars.

I got it on my bucket,the damn thing rocks and sounds good.
