Product Description

Unlock more of the 6.2L supercharged LT4’s performance and sound with the Kooks 1-7/8” Long Tube Header and GREEN Catted Exhaust Kit for the 2022–2026 Cadillac CT5-V Blackwing.

This comprehensive system replaces the restrictive factory exhaust components ahead of the rear mufflers with 1-7/8” long-tube headers, 3” GREEN catted connection pipes, and a full 3” X-pipe. The system then connects to the factory exhaust near the rear axle, allowing you to retain the OEM valved mufflers and factory Active Exhaust functionality.

Constructed from 304 stainless steel with mandrel-bent tubing, this Kooks package is designed for high-performance street builds looking for improved exhaust flow without eliminating the versatility of the Blackwing’s factory valved rear exhaust.

For owners planning additional LT4 modifications such as an intake, pulley upgrades, ported supercharger, ethanol-based fuels, or ECU calibration, the increased exhaust capacity also provides a strong foundation for higher-output combinations.

Product Features

  • 1-7/8” Long-Tube Headers – Designed to improve exhaust flow from the supercharged LT4 while providing the capacity needed for both stock and modified CT5-V Blackwing combinations.
  • Kooks GREEN High-Flow Catalytic Converters – The included 3” GREEN catted connection pipes provide a high-flow catted configuration for owners who don’t want to run a competition-only catless system.
  • Full 3” X-Pipe – Replaces the restrictive factory mid-section with a large-diameter X-pipe designed to improve exhaust flow and create a more aggressive LT4 exhaust note.
  • Retains Factory Valved Mufflers – Rather than replacing the complete rear exhaust, the Kooks system connects near the rear axle and retains the Cadillac’s OEM valved mufflers.
  • 304 Stainless Steel Construction – Mandrel-bent 304 stainless tubing provides excellent durability, corrosion resistance, and consistent exhaust diameter through the bends.
  • Complete Header-to-Rear Exhaust Package – Headers, catalytic converters, X-pipe, gaskets, clamps, and installation hardware are included, providing a comprehensive upgrade rather than requiring individual exhaust components to be pieced together.

Why Upgrade?

The CT5-V Blackwing’s supercharged 6.2L LT4 responds exceptionally well to improvements in airflow. As horsepower increases, reducing restriction on both the intake and exhaust sides becomes increasingly important.

The Kooks 2313F432 package addresses a substantial portion of the exhaust system at once.

The factory exhaust manifolds are replaced by 1-7/8” long-tube headers, followed by large 3” GREEN catted connection pipes and a 3” X-pipe. This provides a higher-flow exhaust path from the cylinder heads all the way to the factory rear mufflers.

Retaining those OEM mufflers is an important advantage on a street-driven Blackwing. You gain the flow, tone, and performance potential of a long-tube header and 3” exhaust package without giving up the factory valved exhaust system that helps make the CT5-V Blackwing such a versatile performance sedan.

For modified cars, the package also provides additional exhaust capacity for combinations incorporating cold air intakes, larger throttle bodies, pulley upgrades, ported superchargers, camshafts, ethanol fuels, and custom ECU tuning.

Installation Note

Kooks specifies that the factory exhaust must be cut during installation because the new 3” system connects to the OEM exhaust near the rear axle.

However, no welding is required. Kooks includes the necessary clamps, gaskets, and hardware to complete the installation.

Professional installation is recommended due to the scope of a long-tube header installation and the need to properly locate and cut the factory exhaust.

Give your CT5-V Blackwing the exhaust flow its supercharged LT4 deserves with Kooks 1-7/8” long-tube headers, GREEN high-flow cats, and a full 3” X-pipe—all while retaining the factory valved rear mufflers.
