Replacing your stock Manifold and Up-Pipes should be your first step in building a high performance exhaust system. These exhaust manifolds were co-designed by Honeywell (Garrett) and PPE using CAD software to maximize flow characteristics. The up-pipe bellows are high flow, internally sleeved and aircraft grade! Our Race High Flow Exhaust Manifolds and Up-Pipes lower EGTs, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Perfect for upgraded turbo systems and nitrous equipped trucks with high EGTs.


  • Cast hi-sil moly iron high flow manifold construction
  • Significant reduction in drive pressures
  • Free flowing Stainless Steel Inner Liner Bellows
  • Stainless Steel 11-gauge .120-inch wall diameter Up-Pipes
  • Built in bosses, pre-drilled and tapped 1/8” NPT for EGT gauge sensor
  • Substantial performance increase for upgraded turbo systems and/or nitrous injection

For use in NON-EGR Off-Road Applications.

Great looking! The parts looks VERY high quality. Install was smooth with no fitting issues. Turbo spools WAY faster and egts are down about 125deg, feels like it pick up a few horses (seat of the pants). Great price with free shipping Thanks XDP and PPE!!! Ryan
