XDP XD342 Driver Side High Flow Exhaust Manifold 01-16 GM 6.6L Duramax

Replace your restrictive driver side exhaust manifold in your 2001-2010 GM Duramax for enhanced exhaust flow and lower EGT's with the XDP High Flow Manifold. The factory manifold in your 2001-2010 Duramax has a "dented" or "kinked" driver side manifold that creates a massive restriction. For 2011-2016 Duramax owners, this product is a stock replacement as GM updated the manifold in 2011. Each manifold features a durable cast construction and includes gaskets needed for installation.
