MBRP's 4" 16-gauge 409 stainless steel mandrel bent down-pipe for 11'-14' 6.7L Powerstrokes offers improved heat retention & 20% better flow than the OE restrictive stock down-pipe. The lower restriction helps lowers EGT's, increases throttle response and provides power gains up to +21HP and +24 lbs/ft. of torque. The free flow design has the added benefit of slightly deeper and more pronounced exhaust note. Built from heavy duty 409 their performance exhaust systems offer uncompromising quality. Unlike other diesel upgrades, this one is 50 state street legal & C.A.R.B. approved per EO # D-763-1. Installation is a breeze thanks precise bends and the two piece design.

Product Benefits:

  • power gains up to +21HP and +24 lbs/ft. of torque
  • Improved throttle response and fuel economy
  • Lower EGT's
  • 4" diameter mandrel bent 409 stainless steel tubing
