2016 D3 Cadillac CTS-V w/American Racing Headers

D3 Cadillac recently teamed up with American Racing Headers to test out their newest creation for the 2016+ Cadillac CTS-V. This already potent hot rod Cadillac packs 640HP in stock trim using the vaunted LT4 engine. The guys at ARH created a 1-3/4” primary long tube header system with high flow cats matted to the OEM muffler system. The results on 91 pump gas was +34HP & 46TQ without any tuning done. The vehicle exhibited great power under the curve without compromising sound quality. With tuning you can expect even more power and torque to achieve over 700BHP!!
