• Verified Vehicle Compatibility: Designed specifically for GM LS truck engines. Compatible with Chevy Silverado 1500 and GMC Sierra 1500 2002-2013 (4.8L, 5.3L, 6.0L, 6.2L). Also compatible with Heavy Duty Silverado and Sierra 2500HD 3500HD 2007-2016 (6.0L V8) and 2007 Classic body styles.
• 304 Stainless Steel Construction: Manufactured from high grade T304 stainless steel with a polished chrome finish. The 16 gauge tubing thickness provides resistance against high thermal stress, rust, and road corrosion compared to standard cast iron manifolds.
• Precision Laser Cut Flanges: Features a heavy duty 3/8 inch thick cylinder head flange. This machine cut surface ensures a flat, flush fitment against the engine block to maintain a tight seal and prevent exhaust leaks or warping.
• Optimized Flow Dynamics: Engineered with 1-5/8 inch primary tubes merging into a 2-1/2 inch collector. This shorty design reduces backpressure and improves exhaust gas efficiency for consistent engine performance from idle to mid range RPM.
• Direct Replacement Hardware: Kit includes one pair of manifolds for left and right sides, multi layer gaskets, and required mounting bolts. Designed as a direct bolt on replacement for stock equipment. Professional installation is recommended for proper alignment.
