Gibson Exhaust GP126S-1 Stainless Steel Short Tube Performance Header Pair

The Gibson Performance Exhaust GP126S-1 is a dyno-tuned, short tube stainless steel performance header set engineered to unlock more usable horsepower and torque across low and mid-range RPM — exactly where truck and SUV drivers need it most. Designed as a direct bolt-on replacement for restrictive factory exhaust manifolds, these headers dramatically improve exhaust flow and engine breathing while also reducing operating temperatures for a longer-lasting engine.

Construction & Materials:

• Heavy-duty 409L stainless steel construction — built for durability and corrosion resistance
• 16-gauge, 1.5-inch diameter mandrel-bent primary tubing for smooth, unrestricted exhaust flow
• 2.5-inch collector outlet diameter for optimal scavenging efficiency
• 3/8-inch heavy-duty laser-cut port flanges — precision cut to prevent warping and eliminate leaks

Key Features:

• Short tube, direct-fit design — bolts directly to the factory crossover pipe with no welding required
• Uses OEM-style connections for a clean, hassle-free installation
• Compatible with both lowered and raised vehicles; suited for street and off-road use
• 50-state street legal — meets all EPA and CARB emissions requirements (CARB E.O. D-411-13)

• Backed by Gibson's Lifetime Limited Warranty (stainless steel products covered for internal rust-through)

What's Included:

• Matched pair of stainless steel short tube headers
• Premium gaskets

Gibson Performance headers are dyno-tested and application-matched for each specific platform, ensuring real-world performance gains come in at the RPM ranges you use every day. Whether you're towing, hauling, or cruising, the GP126S-1 delivers the power, efficiency, and reliability you expect from a premium exhaust upgrade.
