Lexx MXe Spark Arrestor Insert
Richard C. in CA
Good value spark arrestor for your MXe pipe.
I needed this in order to removed the quiet insert/SA and still be USFS-legal. it looks well-made and was easy to install. Time will tell how durable it is.

Lexx MXe Slip-On Silencer With Mid-Pipe
chad in NV
Great sound, price, fitment, and quality. Rocky Mtn...
This Lexx silencer has it all. The deep rich sound, easy installation, awesome price. it comes with 3 varying baffle sizes so you can control the sound if too loud (no such thing) and spark arrester built into baffle for the trails. My '17 WR450 came to life when I installed this silencer along with the GYTR CCU upgrade. I highly recommend getting these items through Rocky Mountain- They get the right part first, no guess work- And this pipe looks great!

Lexx MXe Trail Saver Quiet Core Insert
David in CA
Much better now
When I bought my son a 2001 WR250F it came with a Big Gun muffler on it. That thing was so loud We got kicked out of a riding park. I could not find a new one for his bike so I tried this out had to cut the flange to make it fit. Now I can not hear him behind me any more which is a good thing just had to do a little carb jetting and the bike runs great/
