TSP is proud to now offer the 2009-14 CTS-V headers for the sedan, coupe, and wagon to our TSP line of exhaust products. The TSP CTS-V headers are a true long tube design, not a mid-length like some of the competitors. TSP headers were tested in-house to perfect the design for maximum clearance and power gains. The '09 - '14 CTS-V headers also come with a button head bolt for improved clearance on the middle of the steering shaft (3rd bolt from the bottom).
