quiet performance exhaust for yfz 450.....anyone??

[yfzrider310]

Pretty much what the title says and im not looking to spend more than $300 but if its a quality exhaust I might pay more. It would be nice if it could be loud and then be quiet with a quiet core or something like that....thanks alot.

it is about 6 inches longer than the race one they make.

like how quiet are we talking....its gotta be like 96 db or below and have some decent hp gains....need it for home and racing

i don't know. i bought it off a freind who had two engines built by rossier in 05 and both exhausts came with 2 silencers and he never used either one.he got these with the engines for one flat track in the area that requires 98 db. i was going to use it on a hybrid project that never got finished.so i don't know how quiet it realy is. it is a lot longer than the loud one is.
