Product Description

Unlock more performance and a more aggressive exhaust note from your 2009–2013 C6 Corvette LS3 or Grand Sport with the Kooks Long Tube Headers & X-Pipe Package. Engineered to improve exhaust flow and reduce restriction, this complete system replaces the factory exhaust manifolds and front exhaust section with premium stainless steel long-tube headers and a high-flow X-pipe.

Available with 1-7/8" or 2" header primaries, the system can be tailored to both street-driven Corvettes and higher-horsepower builds. Choose between competition-only catless connections, high-flow catalytic converters, or Kooks GREEN catalytic converters to match your intended application.

Manufactured in the USA from durable 304 stainless steel, Kooks headers feature precision-engineered tubing designed to improve exhaust evacuation, support horsepower and torque gains, and enhance the naturally aspirated LS3's exhaust note.

The included X-pipe transitions to the factory-style 2.5" rear exhaust, allowing owners to retain a compatible OEM or aftermarket axle-back system.

Why Upgrade?

The 6.2L LS3 found in the C6 Corvette and Grand Sport is an excellent platform for naturally aspirated performance upgrades, but the factory exhaust manifolds and catalytic converter arrangement can become restrictive as airflow demand increases.

The Kooks Long Tube Header & X-Pipe Package addresses these limitations by replacing the factory manifolds with larger, performance-oriented long-tube headers and a matching high-flow exhaust section.

Long-tube headers help improve exhaust scavenging by allowing exhaust pulses to travel through individually tuned primary tubes before entering the collectors. This can improve cylinder evacuation and support increased horsepower and torque, particularly when combined with a proper ECU calibration.

For a relatively stock LS3 or a Corvette equipped with basic bolt-on modifications, the 1-7/8" header configuration offers an excellent balance of exhaust velocity and flow.

For more extensively modified combinations featuring ported cylinder heads, aftermarket camshafts, larger throttle bodies, intake manifold upgrades, or increased engine displacement, the 2" primary configuration offers additional flow capacity.

The included 3" X-pipe further improves the exhaust path while creating a deeper, more aggressive exhaust note. Owners can also retain their compatible factory or aftermarket rear exhaust system, making this package an excellent foundation for a complete C6 exhaust upgrade.

Whether you're building a street-driven Grand Sport or a higher-output LS3 Corvette, the Kooks system delivers the construction quality, exhaust flow, and performance potential expected from a premium American-made header package.

Unlock the performance and sound of your C6 Corvette LS3 with Kooks Long Tube Headers & X-Pipe—available in 1-7/8" or 2" configurations with multiple catalytic converter options to match your build.
