A vehicle's exhaust system is one of the most important factors in engine performance. The pipe size and flow rate have a direct effect on horsepower potential. With a non-sufficient exhaust flow, your engine's full potential will not be realized. The exhaust system finalizes and determines the full potential of a modified engine. A high-performance exhaust system will allow additional engine modifications to come alive. Thermal Research & Development has been working closely with import racing professionals to configure optimum exhaust products for both the street and the racetrack. Thermal Research & Development hand crafts their exhaust systems with maximum horsepower as their top priority. Thermal exhaust systems are made of stainless steel and are mandrel bent for high flow through bend areas.

Classic Exhaust Systems Thermal Research & Development Classic exhaust systems are designed for bolt-in applications and have a deep, throaty sound. Classic systems are tuned towards the upper mid-range and top end and are recommended for the more aggressively built vehicle.

Stealth Exhaust Systems Thermal Research & Development has recently introduced the STEALTH line of exhaust systems, built specifically for street performance. These systems are designed to create a mellower exhaust sound. These systems feature the same great look and quality as our Classic systems. STEALTH systems are tuned towards low to mid-range power and are recommended on mildly modified vehicles.

Turbo Exhaust Systems Thermal features a line of exhaust systems designed for the Turbocharged Acura and Honda. These systems are made of 3" mandrel bent stainless steel pipe and require some slight modifications to your high-flow catalytic converter. We include an extra 3" flange for an easy installation of the exhaust system. These systems are a true 3" and will not connect to a stock catalytic converter.

Universal Mufflers Thermal Stainless Mufflers have a sound absorbing design for maximum performance.

Stainless Muffler Tips Thermal Exhaust Tips are built from T304 stainless steel and hand crafted with a high luster polish.
