Y-pipe for LMM

This Up-Pipe works with the PPE performance exhaust manifold. This Duramax Up-pipe will give your GMC Sierra or Chevy Silverado significant reduction in exhaust back-pressure and helping increase flow. This Free-flowing stainless steel inner liner bellow improves the overall look and performance of your GM 6.6L Duramax. The Up-Pipe is made with stainless steel 11-gauge .120-inch wall, 2-inch OD and will give faster turbo response with lower exhaust temperatures. NOTE: This product is intended as a replacement for the single up-pipe from the PPE High-Flow Manifold and Up-Pipe Kit (SKU 116111800).
