I have a 2000 warrior and on the weekend I fitted a Pro Circuit T4 pipe as well as Maxxis All Trak rear tires.

What a difference to the handling and cornering as well as the acceleration and mid range. The bike has far more quicker response. I did not rejet or drill air box etc.

Can't do doughnuts the way I did with the stock dunlops though ! does wheelie easier though.

Cool!I've been trying to find out if a pipe would help but everybody wants me to get a piston/cam!Also is it any faster and do you suggest that stuff to other people?

 

No doubt the piston/cam route will get the biggest hp gain but also for the biggest buck.A
pipe will get u a reasonable gain which is noticable.i would go the pipe route and later u can do the engine mods.

 

An aftermarket pipe is only going to perform as well as you make it. If you get the aftermarket pipe, you should also rejet, and get a pro-design kit with K&N.

The biggest problem with the warrior is it's handling, you should tackle that problem first, maybe with different tires & an axle, then dump some cash into the motor

just my advice.

 

Sounds like you got quiet a bit of an improvement on your ride. Just wait till you get some front tires on it!! These will make another hugh difference in your cornering ability!
