I ended up using a Supertrapp IDSII on my warrior. Really let the low end grunt come alive. It is a tuneable exhaust and you can set it up for your style of riding. If you like to ride fast, put in more discs and let it breath (will be a bit louder this way) if you like to roll up to a log and crack the throttle and wheelie over it, use less discs (now a bit quieter). Either way, adding a pipe will make your bike run a bit leaner. Make sure to adjust for this.

If your bike is completely stock, changing to a K&N Air filter will make a noticeable difference as well.

Ride on.

 

I used to run an IDSII on my warrior as 95wolv knows. I think if I had it to do over again I would either go with another IDSII or maybe look at putting an HMF on it. I have grown pretty fond of the HMF system after running it on a KFX400 and BajaX

I used a White Brothers e-series promeg on my old warrior and had no complaints... although it wasn't like a miracle when I added it. I've heard nothing but good things about Pro Circuit and CT ... My plans for my YFZ are for the Pro circuit Ti-4 this time around. Nothing against White Brothers but I'm still looking for something to wow me.
