    The FMF "Gnarly Desert" pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. When looking to add 4-stroke tractor like torque to your 2-stroke and you need a pipe to withstand the harsh elements, this is the pipe for you. Strong and rugged, this aggressive pipe dishes out handfuls of torque and bottom to mid-range pull needed for late model 200cc through 500cc machines and the rigors of the off road domain.
  • Nickel plating is an FMF trademark and has been ‘copied’ by everyone making it the most imitated expansion chamber in the world.
  • Super strong 18 gauge steel construction makes it GNARLY!
  • O-Rings Included.

Pipe is the best there is

Comments On Sep 21, 2013:The original was working perfect and will go up on Ebay or Craigslist since it was only cosmetic for the purchase. Nobody likes to ride around with dented up equipment. Well that is the only reason for the purchase -- cosmetic. In the world of exhaust, FMF is the best.

Good quality product

Comments On Mar 19, 2011:Put this pipe on a 1991 KX500, makes awesome power. Increased bottom end and mid range-no loss on top. Combine this with a fresh top end and a reed spacer to make tremendous but usable power with a 500 two stroke.

Good stuff - If you have the 220 get Gnaryl

Comments On Feb 27, 2011:Taken from ferdette racing, KDX guru: "I recommend the Gnarly "REV" PIPE for the more experienced rider and all other riders riding in fast terrain with good traction. This pipe will improve performance throughout the power band with the most noticeable hit in the mid-range and up. I recommend the GNARLY "TORQUE" PIPE for the less experienced rider and more technical terrain because it also improves performance throughout the power band but with a more manageable power delivery. The torque pipe is not recommended for the 220?s."

Greatest investment

Comments On Oct 23, 2007:The pipe exhibits excellent weld quality and product design. The power that this pipe added to my bike is phenomenal because of its free flowing nature as compared to my stock pipe. The pipe is still lustering and shining to this day also, and I have had it through some tough and dirty rides. Best investment for my bike I ever made, 2001 kdx220.

Good Pipe, great power

Comments On Oct 22, 2007:Overall this is good pipe. I think as good as any other out there. This pipe keeps the DB's down and produces great power in all ranges. I am not a big fan of the polished exterior but short of that I highly recommend!
