Best 2007 yz450f exhaust

Hi guys just curious what do you guys think would be the best exhaust for my 2007 yz450f? the stock exhaust is waay to quite and gutless i live in the middle of no where so sound isnt an issue i just got the fmf power bomb and it helps but still looking for more bottom end torque i heard leo vince is pretty good or two brothers but i haven't been able to find any leo vince online for my bike any help would be great thanks guys

I only tried one, Akrapovic Evolution.

But maaaan I will never use another exhaust, this thing just sounds good, to damn good. It's like porn for my ears.

Although I noticed it added more top end than bottom...

And the build quality ... much better than my friends fmf, pro circuit etc.

Stock with the end removed and a commodore crank pulley welded in made a nice "sports exhaust" on my friend's old TT.

 

Was ear bleedingly loud and added -3hp. Perfect.

RMATV has the DRD full system for $383 with coupon.

That akropovic looks too dope lol but i cant find any exhausts that will fit on my 07 and their so expensive lol

What do you mean by crank pulley?

Pulley mounted to the crankshaft that turns the fan belt, water pump, power steer, AC etc.
