What is the best pipe to put on a 1999 Yamaha Warrior that is legally loud. I do mostly aggressive trail riding, woods trails, and a little hillclimbing. I was considering the White Bros E-series or the kit from alba racing. Either way I plan on getting the torque stuffer from Alba also. I'm also considering changing my front sprocket down one tooth. Just wondering what other Warrior owns had to say.

P.S. I don't see why every one says that the 400EX is so much better than and faster than a Warrior. I run right with the stock EX's my friends have, in the woods, on trail, and not far behind in drags.

agree dude 100% mine will stay with the 400ex. my cuz got 1 he has white bros. e-series pipe, and rejeted. i stay right with him.i have and lrd complete pipe on mine yes it loud. louder than the e-series. just a straight pipe. i like it in the woods.

Me too i can keep up with all my friends 400ex's in the woods and on the trails. Most of them have spent quite a bit on pipes too. I've got a FMF Mega MAx 2 on my warrior. I tooke the quiet core out and just left the diffuser disks and the end cap on it. I do get what i fell is a better result racing with the cap off but for the trails it's better with the cap on.
