i have a recon and want a new exhaust, which one should i get. What is the whole jets thing and how much should i change them?

 

Go for a Pro Circut they do great on the Recon

 

Yeah they're nice, how do they sound and where does it improve the power at Low, Mid, or Top end?

 

I have a K&N with outerwears and an FMF MegaMaxII, with 6 discs. Perks the little bike up quite a bit!!

As far as jetting, you are adding more air, so you need to add more fuel, to keep the ratio of fuel to air correct. If this isn't something you are familiar with, spend the money and have it done by an experienced machanic. Jetting is more art than science. Don't neglect the jetting, you will be lean, and burn up your engine!!
