What exhaust will give my 2011 KLX250s the highest hp boost.

If I put on an aftermarket exhaust will I need to re jet and will it melt the back of the blinker?

with any exhaust you will need to re jet or you will loose power.

If you are really looking for increased power, for less money, keep your stock exhaust, open it up a bit, and buy a Big Bore from Bill Blue. You'll have to rejet. But, power will be much more than what you'll get from a new exhaust system.

The big bore kit is the best exhaust mod ?
