You HAVE to re-jet the carb anytime you modify the air flow or exhaust. If you don't, you will run rich and foul plugs alot and it will run like . Or it will run lean and burn up valves. Not only that, but you lose power if you don't. If you put on a performance pipe, and don't re-jet, you will actuctaly have less power than stock.

Not always true. Alot of factory settings are rich so when you pipe them they lean out and run like the devil. The problem is as you stated, you can screw things up being to lean.
