I am sure this has been covered a few times but I ran a search and did not find what I am looking for so I now put this up for discussion. I am thinking of getting a new pipe for the WR450. I am currently running the stock pipe with a GYT-R insert, the 40 dollar model. I mainly ride technical single track, double track and the such..."Rocky Mountain Riding" if you will. Rarely do I find myself on a track. I want a good pipe that will give a bit of grunt but I am not looking to give the tree huggers here in Jackson any more reason to close more riding terrain. Therefore it has to be on the quiet side of things. I see many people are running the FMF Q, Big Gun etc. I am thinking about going with Yamaha GYT-R pipe. Anyone running this? Any feedback would be great.
