Description

The HSP Diesel Ceramic Billet Manifolds offer a performance upgrade over restrictive factory exhaust manifolds, specifically designed for 2001-2016 Chevrolet and GMC Duramax trucks. These manifolds aim to improve power by addressing the inherent flow limitations of the stock components. Machined from durable 1018 steel with CNC precision, these manifolds feature a high-flow, low-profile design that enhances exhaust flow. A key benefit is the elimination of the common flow restriction found in the driver's side factory manifold. The ceramic coating provides superior heat protection, with a rating of up to 2,000°F. Compatibility with factory-style up-pipes is maintained, simplifying installation. The kit includes all necessary new gaskets and grade 8 hardware. Fitment is provided for various Duramax engine codes: LB7 (2001-2004 VIN Code 1), LLY (2004.5-2005 VIN Code 2), LBZ (2006-2007 VIN Code 2 or D), LMM (2007.5-2010 VIN Code 6), and LML (VIN Code 8). The engine code is determined by the 8th character of the VIN, and the model year by the 10th character. HSP Diesel backs this product with a "No BS" Limited Lifetime Warranty, reflecting their commitment to quality and customer support.
