MRD pipes are hand-built from 18 guage 304 SS and 6061 aluminum, they are tig welded by hand by owner Dave Harryman. These are not over priced stamped out, mass produced pipes, they have a high quality hand fabricated look. MRD builds their pipes from stainless steel because it is the best material for exhaust systems. SS holds more heat in for better exhaust velocity, it does not dent as easily as Titanium, and it does not require loose spring mounting to keep it from breaking. MRD pipes have superior dimensions and flow better than stock, resulting in noticable power gains. Endcaps are bolted for easy removal when changing inserts or repacking.


  • Tapered design, made from 304 Stainless & 6061 Aluminum
  • Straight, 2.25" high flow core
  • Hi temp spec 31 packing
  • Bolted endcap
  • 14" muffler section
  • 3-4hp peak gains

This pipe is made from bigger diameter tubing and has a bigger muffler core than the PROCOMP that allows a fully modified DR-Z400 engine to develop maximum HP. It can be run with a quiet core insert and spark arrestor and it works great on near-stock engines as well.
