I have about 270 dollars to spend. What would be the best thing I could get? I was thinking of exhaust. Are there other mods that would equal or surpass the performance gains that exhaust would bring without spending more money? Thanks.

The pipe is a good start. One you have a pipe you can start your other engine mods. You don't wanna get nes cams and pistons and carbs without a pipe. I would suggest Big Gun because the have just as much power as FMF and White Bros. but is quieter which is better.

Tranz455am,
The first thing I did with my Warrior was to dump the pathetic filter system that Yamaha has used for the last decade or so, and replace it with a Pro Design Pro Flow kit. This kit mounts an aluminum billet directly to the air box & the foam filter system clamps to it. When it is on, it's ON!, unlike the stock thing which is seated by the lid of the box, presumably. The kit is about $89 to $99 depending on the dealer.
You will see a marked improvement in engine performance, but more importantly you will do wonders for the life of your engine. You will have to rejet to one size fatter on your main for the improved air flow.

I've already modified the air box. I took off the lid and fabricated a system to hold the filter in place. (Heavy duty tape made of aluminum I believe. Costs a crap load and won't let go.) I've also taken the baffle out of the muffler. I cut the tip of the muffler off, the part that tapers down to about 3 inches, and pulled the baffle out. I have already rejet to 155 main.

I think I'm going to go with exhaust. Then maybe a cam?

Oooo, what now cal? In your face! He already modified the air filter. J/P Cal!
Tranz455Am: The pipe is good then the next one you could do is the cam and all the other 4-stroke crap that I hate.

Aren't I real informative today

I highly recommend you don't touch the engine till there is a pipe on it.

That's what I don't want to do. How much is the e-series? I'm having some trouble finding the price. Thanks.

Had a 99 Warrior. (bought a 400ex) Anyways, I totally disagree with the above posts. I got a 10.25 to 1 Wiseco Piston and a White Bros 390 cam and Titanium valve springs. It made a big improvement and didn't make it much louder at all. Later I bought the White Bros pipe and it made it even faster. Those parts are about $300, but labor would obviously be more $$$ than install of a pipe.

 

I just bought a E-Series Pro-Meg from Moto Man for $229.00--that's about an average price you'll find in the mags. It bolts right up and is rather loud with all 12 supplied discs, but my Warrior is now a lot more responsive on the bottom end than stock. To be honest though, I was hoping the pipe was going to give me more power than it did. I side with Cal (hot_shoe_cv) on the filter issue, as the best mods I've done so far after the pipe are a Pro Flow filter kit with a vented airbox lid--these two items with a bigger main jet really woke up the bike, especially on the bottom. Sorry to be blunt though, you can tape the crap out of the factory filter setup and it's still pathetic as heck, and as for me I'd be scared to run the stock filter without the lid. Do yourself and your Warrior a favor by getting something that filters and breathes better than the stock filter--you could also run a K&N filter with the Pro Flow adapter rather than a foam filter.
