Well........... I just installed a LRD exhaust on our 09 and re-jetted it. It definately help.

I dont care for the FMF, just my opinion. We had really good luck with a Big Gun on a stock bore motor. Some friends of ours have used the Pro Circuit on both stock and modified motors. We run a CHP pipe but those are for big bore/big valve motors

i took a big gun core and put it in the fmf and it works great. the core from big gun is only 15$. getting the old crap out of the fmf is fun but worth it.
