A couple of months ago, i bought my first quad, a 250EX. I'm looking to hop it up with an aftermarket pipe, but i don't know what company to go with, and whether to go with a slip on or a full pipe. I've been looking at the pro-circuit t-4, dg stage one xcellerator, or a white bros. e series. help me out and tell me the best setup for my machine.

 

I put a Graydon Proline exhaust system (both header pipe and muffler) along with a K&N Air filter and a new jet. It seemed like it helped it rev faster and pull harder accelerating but it would hit the rev limiter right away so that kinda sucked.

 

That means that your accelerating faster.
