    MRD pipes are hand built from 18 gage 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. Highlights: - Tapered design, made from 304 Stainless & 6061 Aluminum - Straight, 2.25" high flow core - Hi temp spec 31 packing - Bolted endcap - 14" muffler section The MRD Z-Pro mod pipe was developed with the help of respected engine builder / tuner Eddie Sisneros of Sisneros Speed Works. This pipe is made from bigger diameter tubing and has a bigger muffler core than the PROCOMP that allows a fully modified DRZ400 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. https://www.youtube.com/watch?v=KoE9LF5MQjk

    Yoshimura RS2

    9 reviews

    DESCRIPTION The Yoshimura RS-2 Stainless Aluminum Exhaust is delivered with a complete kit that includes mounting hardware and well written installation instructions. Yoshimura is well known in the ATV exhaust industry and in my opinion this years RS-2 exhaust system is on par with past stainless and aluminum models made by Yoshimura which just happens to mean they are among the best available for your sport ATV or Quad. Yoshimura ran a dyno test of the RS-2 Full Exhaust System on a 2009 YFZ 450r ATV vs the stock exhaust system and muffler and as you can see the Full Yoshimura RS-2 Stainless Aluminum Exhaust system yields an increase of 2.3 maximum horsepower and 1.6 lbs of torque. The dyno test on the Yosh RS-2 exhaust was run with a 96db sound insert USFS approved spark arrestor but 94db and 99db inserts are also available. Power gains lean towards improved full throttle high RPM response meaning they allow an ATV engine to breathe more freely at top speed.
