The TH-SS was a limited-edition car produced by GMMG, which also produced special Camaros for enthusiast Chevrolet dealers like Berger and Dale Earnhardt. The Marietta, Georgia, company modified this 2002 model's LS1 to produce 380 hp and 400 lb-ft of torque with the help of a carbon-fiber airlid, ported manifolds, chambered exhaust, a high-flow MAF sensor housing, and a reprogrammed engine computer.
