The title says it all. Which mod will yield the most noticable difference in performance? Thanks.

 

Slip on exhaut along with an aftermarket air filter w/ adaptor to run without the lid, if you plan to run with the lid off buy an outerwears cover for the filter. You'll have to rejet.

The good thing about the raptor 350 VS the warrior:

The raptor 350 crankcase hose is connected to the airbox not the lid like the warrior, otherwise you would need to purchase another smaller filter to run with the lid off.

I have a Pro Curcuit T4 on my warrior with a K&N Airfilter no air box lid (w/ outerwears), and love it. Its a night and day difference from the stock pipe to the T4. Its not REAL loud either.

I got a buddy with a raptor 350 with a HMF (Blue) slipon and a K&N air filter (w/ outerwears) and also its night and day. Really in my opinion if I had a raptor 350 one of the first things I would buy are handle bars. I think the stock bars are very uncomfortable. He replaced his stock bars with a set of pro taper (I think contour bend) and they feel MUCH better.

Sorry for the short story. Hope it helps..

 

Pelphrey...Man...you hit the bullseye...Thanks!

 

Tires. The stockers suck. First ride out I sliced a rear tire. Next ride out I wasted a front. Buy a nice set of six ply tires, you'll never regret it. You should see some of the crap I run over at full speed, never a problem. You can't go fast on flat tires.....lol.
