Give your Blackwing an exhaust to match its V8
The LT4 makes a Blackwing feel special every time you use it. Kooks long tube headers let you develop the exhaust around that engine, with mandrel-bent 304 stainless primaries and a choice of 1-7/8-inch or 2-inch diameter for your 2022-2026 CT5-V Blackwing.
SKUs: 23132400, 23132600
Choose around your engine specification
23132400 has 1-7/8-inch primaries; 23132600 has 2-inch primaries. Both finish in 3-inch TORCA collectors. The 3/8-inch laser-cut flanges use oval ports and the factory bolt pattern, matching the LT4 application.
Ready for your installer
Both header options include 755897 GM gaskets, CAS-115999 O2 extensions, BK113 header bolts and two 3-inch TORCA clamps. Fit them with the matching Kooks header-back exhaust, with the calibration and installation planned for the complete system.
