Thermal Research Muffler Tip - 4" Dia X 8" Long X 3" Inlet Angle

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 over all else.

Thermal exhaust systems are made of stainless steel and are mandrel bent for high flow through bend areas.

Thermal Research & Development is always quick to remind people of this: 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.
