Product Details

The Kooks Headers 2151H420 is a complete 1-7/8-inch emissions long tube header and catted connection kit built for the 1997–2000 Chevrolet Corvette C5 with the 5.7L LS1 engine. This kit delivers a true bolt-on performance exhaust upgrade without sacrificing emissions compliance, making it ideal for street-driven C5 Corvettes.

Kit Includes:

  • 1-7/8" x 3" stainless steel long tube headers with emissions sensor fittings (O2 bung ports)
  • 3" x 3" catted stainless steel X-pipe with high-flow catalytic converters
  • Designed to connect to the 2-1/2" OEM-style exhaust system

Key Features:

  • Constructed from high-quality stainless steel for long-lasting durability and corrosion resistance
  • Emissions-legal design retains oxygen sensor ports for proper ECU operation
  • Long tube primary design maximizes exhaust scavenging for improved horsepower and torque
  • High-flow catalytic X-pipe improves mid-range and top-end power while maintaining emissions compliance
  • Handcrafted in the USA by Kooks Headers & Exhaust

Kooks Headers & Exhaust has been a leader in high-performance exhaust manufacturing since 1962, with championships earned across the NHRA, IHRA, NMCA, NMRA, NASCAR, and SCCA. The 2151H420 is a direct-fit solution engineered to drop in on the C5 Corvette platform and deliver real performance gains right out of the box.
