For dune riding you could also try DMC 916's, very very underrated exhaust. A builder did a comparison on them and everyone else and posted it here a while back, they did very well
I've asked to be an Admin multiple times being I'm on here everyday and have spidey senses when it comes to spammers. Tyler won't do it though as he's worried people won't see the need for him anymore.
IMO anything you do will affect the chrome. You can try compressed air, but that’ll require you to block both ends of the pipe. Besides that, not much. Sent from my iPhone using Tapatalk
