Well, my 2 cents... Since you just got your atv, I would highly recommend racing it with the stock exhaust. After some races, then you can decide on which modifications you wish to do first to your atv. (ie. tires, kill switch, shocks)

Note: It is not a requirement to have an aftermarket exhaust to race.

I would hate to hear that you bought an aftermarket exhaust that would not complement possible additional engine modifications you may make in the future.

Good luck racing... And welcome to Exriders.com!:)

Ex'r Marlin has a point. If you are going to race a stock engine, which there is nothing wrong with that. It is better to do supension and handling mods first. Such as tires, shocks, axle, ect. Then as you get a handle of that then start working on the motor.
I wish I would have done the suspension mods first. Just my thoughts. :)

You will find people on here that like many different pipes. e-series is very popular, also lrd and ct. The most important thing I think everyone would agree on is that you need to add a hi-flow air filter and re-jet at the same time that you add a pipe. Adding a pipe alone will make your bike run very lean.

I agree race the bike a few time first. That will let you know were you feel it needs to be improved( motor, suspension, tires etc) you may like the stock power but hate the tires, or the shocks.:D
