PPE’s Manifolds and Up-Pipes are designed to maximize power and flow characteristics.


The Up-Pipe bellows are internally-sleeved, made from aircraft-grade 304 stainless steel and designed with an increased inner diameter for higher flow. The entire Manifold and Up-Pipe exhaust system is designed to lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy and maintaining reliability.


Kit comes complete with two PPE manifolds, two PPE up-pipes, a PPE down pipe support bracket, PPE 301 stainless steel manifold gaskets and up-pipe gaskets.

  • Up-Pipes made from stainless steel 11-gauge .120-inch wall, with a 2-inch outside diameter
