Bring more V8 character to your C5
Enjoy more of the V8 that makes your C5 special. Kooks long tube headers give its LS1 or LS6 exhaust a purpose-made upgrade, with 304 stainless construction, O2 fittings and 3-inch merge collectors across all three primary sizes.
SKUs: 21502200, 21502400, 21502600
Choose the size for your engine
21502200 has 1-3/4-inch primaries, 21502400 has 1-7/8-inch and 21502600 has 2-inch. Choose around the engine specification and the exhaust you are fitting; we can help you compare the sizes for your build.
Complete it with the matching X-pipe
These Race headers use a Kooks X-pipe. Professional fitting should check the driver-side clutch line, passenger-side power wiring and O2 harness routing as the headers and crossover are aligned, keeping nearby components clear of the hot exhaust.
