Stainlessworks 2004-07 Cadillac CTSV headers
- 1 3/4″ primary tubes with 3″ OD collectors-headers only.
- Long tube design makes great power and mid range torque.
- 3/8″ stainless steel CNC laser cut flanges are port matched to the cylinder head for optimal flow and maximum performance.
- Fits to Stainless Works exhaust but will require some cutting, welding, and fabricating to connect to the stock or aftermarket exhaust systems.
