I just bought a white bros e-series pipe for my quad and i was thinkin if i go in alot of mud will it still work alright, because of the tuning disks. If anyone has any imput drop me a line.

 

It shouldn't hurt it anymore than getting mud in the end cap of your pipe. (neither are good)
Just make sure you clean it out really good when you get back. Does the white brothers pipe give you a noticible amount of power? I'm thinking of picking one up soon.

 

I LOVE it it sounds great, Not too loud that i can't think when its idleing but when you letter rip it barks, the only thing that i don't really like is that to get the most out of the pipe you should get a Power kit and a rev illiminator the pipe lets it breath from the back the filter and power kit lets err suck lots of air and the rev illiminator just let it scream. After that it is a TOTALLY different Quad. I even raced a buddies 2002 GMC 4x4 truck with a 5.3 and it kept up with it most of the way. And other than that all i can say is WOW and it was totally worth getting everything at once.
