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.  We build our pipes from stainless steel because it is the best material for exhaust systems, SS holds more heat in for better exhaust velocity, SS does not dent as easily as TI  and does not require loose spring mounting to keep it from breaking. Our 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
