Kooks Headers 2150H230 1-3/4in. Long Tube Header and Green Catted X-Pipe Connection Kit

The Kooks 2150H230 is a complete long tube header and connection kit engineered for the 1997–2004 Chevrolet Corvette C5 with the GM LS1/LS6 5.7L engine. This kit pairs 1-3/4" x 3" T304 aircraft-quality stainless steel long tube headers with a 3" x 3" Green Catted Stainless X-Pipe, delivering a bolt-on performance upgrade that connects directly to the factory 2-1/2" OEM-style exhaust system.

The Kooks Green Cat X-Pipe is engineered with an enhanced precious metal coating that allows it to function as a high-flow catalytic converter while withstanding the elevated heat levels found in higher-horsepower and forced induction applications. Long tube headers optimize exhaust scavenging for measurable gains in horsepower and torque across the RPM range.

• 1-3/4" x 3" T304 stainless steel long tube headers
• 3" x 3" Green Catted stainless steel X-Pipe
