I am wanting to get an after market exhaust. I have been looking at a WB E-Series or Big Gun. Which one would be suggested. The quad is all stock. I mainly ride on sand dunes, I am leaning toward Big Gun. Also, with the Big Gun exhaust will I have to rejet? to what?

Both pipes are good choices. To get the most out of a slip-on,
it's good to modify the airbox or remove the lid and rejet.
My mods are listed below. Maybe some guys that ride the dunes
alot will tell you what works good for them.

go with the big gun, i love mine, it is light, powerful and simple, compared to a WB. My buddy has got a WB and he already broke the lower mount and he is all the time messing with his jetting, my big gun i set it and run it with no problems

desertratt45, are you saying buy big gun b/c you know the guys who build them? or is it the better of the pipes? the reason why I like the WB-E-series Pro Meg is because it is adjustable, along with all other e-series pipes. Being adjustable makes me think the WB will be more "adaptable" to my riding conditions. CORRECT ME IF IM WRONG!!!! Thanks, guys!

well knowing the guys is nice but the pipes are good! the thing i dont like about adjustables pipes are that what it does to your plastic or if you have a six pac on the back it melts the cooler. i just know that i have used big guns on my race bike and they work real well.
