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. Also improves performance and fuel economy of engines with upgraded air/fuel systems.

• 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
