A straight pipe will give you some performance gain over the stock pipe, because the lack of backpressure will cause it to run leaner. However, too much lean will shorten the engine's lifespan considerably. An expansion pipe exhaust is preferable in every way to a straight pipe.

My bike runs fine. I was actually running it somewhat rich for quite a while, and change the needle setting about a week ago.

There has been a very good reason for NOT using it but apparently you don't want to listen to that advice. So good luck with it and I hope you don't ruin your motor too fast with it.

cause it weights alot? a car muffler weighs like 10- 25 lbs. even cherry bombs arent that light. the expansion chamber is light, mounts easily, and increases your power band. if those dont make you want a expansion pipe then your crazy lol.
