Description

The Hellion "Hellraiser" Twin Turbo System (HT-9904GT-TT) is engineered to deliver exceptional power and versatility for the 1999-2004 Ford Mustang GT and Cobra models. This system stands out as a "compound boost" setup when retained with a Roots-style supercharger, a pioneering approach in the Mustang aftermarket. Installation of this system is designed around the UPR tubular K-member, which includes caster camber plates, A-arms, and coil-overs. Using a K-member from another manufacturer may complicate installation and alter the system's intended design. Please note that this product is not legal for sale, installation, or use on a licensed vehicle in California and does not meet CARB compliance. It is intended solely for racing vehicles that will not be used on public highways.
