Pipes are not going to change the intake enough to require a rejet....At the most maybe adjust the idle and A/F ratio.

+1 Freebird - On a stock bike the A/C is what is restricting the total "in/out" air flow, much more so than the exhaust. With the A/C limiting the the amount of air drawn into the carb, the A/F ratio isn't going to change regardless of the exhaust installed.

You do have to rejet for slip ons on the older bikes, they ran so lean off the show room floor you needed to rejet even if you didn't do anything to them.
I would guess your real problem though is dirt in the carb. A 10 year old bike should have the carb pulled and cleaned properly.
Mechanic in a can is only a bandage and my help for a very short time but the real problem will continue to come back.
I'd pull the carb clean it jet it properly 45 slow jet 180 main and change the plugs, heck the plugs alone could be causing this problem.
