4pcs Exhaust Manifold Headers & X Pipe For 05-12 Corvette LS2 LS3 6.0/6.2/7.0L

What is 4pcs Exhaust Manifold Headers & X Pipe For 05-12 Corvette LS2 LS3 6.0/6.2/7.0L?

This complete 4-piece exhaust upgrade kit includes a pair of long-tube headers and an X-pipe assembly designed specifically for 2005–2012 Chevrolet Corvettes equipped with LS2, LS3, or 7.0L V8 engines. Constructed from durable stainless steel, the system replaces restrictive factory manifolds to improve exhaust flow, increase horsepower and torque by an estimated 10–20 hp, and enhance engine sound. The kit is engineered for direct fitment on 6.0L, 6.2L, and 7.0L LS-based Corvettes, including Base, Grand Sport, and 427 Convertible trims through 2013 model years.

Key features

• Stainless Steel Construction — Resists corrosion and withstands high exhaust temperatures for long-term durability.
• 1.75-Inch Primary Tubes — Optimized diameter for improved scavenging and mid-to-high RPM power delivery.
• 4-2 Piping Design — Merges four primary tubes into two collectors, enhancing exhaust pulse efficiency.
• CNC-Machined Flanges — Ensures precise fitment and leak-free sealing on LS cylinder heads.
• TIG and MIG Welded — Strong, consistent welds for structural integrity under high stress.
• Includes X-Pipe Kit — Balances exhaust pressure, improves flow, and deepens exhaust tone.
• O2 Sensor Bungs — Four pre-installed locations maintain compatibility with factory emissions systems.

This system is ideal for Corvette enthusiasts and performance tuners with 2005–2013 LS-powered models seeking measurable power gains and a more aggressive exhaust note. It suits DIY mechanics with advanced welding and exhaust installation experience, though professional installation is strongly recommended due to complexity. Not intended for daily drivers requiring factory emissions compliance in strict states.

How does 4pcs Exhaust Manifold Headers & X Pipe For 05-12 Corvette LS2 LS3 6.0/6.2/7.0L compare?

Compared to stock cast-iron manifolds, this stainless long-tube header set offers superior flow, weight savings, and thermal efficiency. It outperforms shorty headers in high-RPM power and pairs better with modified LS engines. Unlike ceramic-coated headers, it relies on raw stainless durability but may show heat tinting. The included X-pipe adds value over header-only kits, offering balanced scavenging similar to custom-built systems at a fraction of the cost.
