Product Description

The Kooks 2170H420 long-tube header and catted X-pipe kit is a top-tier performance exhaust upgrade for the 2014-2019 Chevrolet Corvette C7 equipped with the 6.2 L LT1 or LT4 V8 engine. With 1-7/8" stainless primaries and a 3" catted X-pipe outlet designed to integrate with factory exhaust, this kit unlocks improved exhaust flow, reduces back-pressure, and enhances engine breathing - translating to stronger mid-range torque, higher peak horsepower, and a more aggressive exhaust note.

Crafted from premium 304 stainless steel with mandrel-bent tubing and precise flanges, the headers ensure durability, corrosion resistance, and long-term reliability even under high stress or heat. The included catted connection pipes allow retention of a more OEM-friendly emissions-conscious setup (versus cat-less headers), and the bolt-on design makes installation straightforward for shops or experienced enthusiasts. The kit is ideal for those building street performance, high-output naturally aspirated, or supercharged C7 Corvettes - delivering a dramatic improvement over stock manifolds in both sound and performance.

Because this is a full header + connection kit, you get a complete path from exhaust ports through to the stock exhaust, which simplifies installation and ensures the system works as engineered. Before ordering, check your Corvette's exact model, year, and exhaust routing - and verify local emissions laws if required. For performance and reliability, tuning after install is recommended to get optimal air/fuel and timing settings for the modified exhaust flow.
