Pacific Performance Engineering 116112500 High-Flow Exhaust Manifolds & Up-Pipes Kit

The Pacific Performance Engineering 116112500 High-Flow Manifolds and Up-Pipes Kit replaces the stock exhaust manifolds and up-pipes on the GM 6.6L Duramax L5P. It is designed to improve exhaust flow, lower exhaust gas temperatures (EGTs) and help the turbo spool up faster.

Key Features:

• Cast high-silicon moly iron manifolds for strength and durability
• Stainless steel up-pipes with internally sleeved bellows and an increased inner diameter for better flow
• Designed to reduce exhaust back-pressure
• Compatible with factory heat shields

Kit Contents (per the manufacturer's installation guide):

• Left and right manifolds
• Left and right up-pipes
• EGR gasket, manifold gaskets, and upper and lower up-pipe gaskets
• Spacers, M8 socket head cap screws and M6 flange head hex screws

This kit is an upgrade for L5P Duramax owners who want better exhaust flow and cooler EGTs.
