Description

The Thermal Research B118-C117 is a cat-back exhaust system engineered for performance vehicles. The tubing measures 2.25 inches in diameter, designed to optimize exhaust gas velocity and flow, while the tip measures a larger 3 inches in diameter for a more aggressive aesthetic and sound profile. The system includes a muffler and resonator, both finished with a mill finish, complementing the polished tip for a refined look. This cat-back system is specifically designed for the 1997-2001 Honda Prelude models, excluding the SH trim. Honda catback exhaust systems were among the first products introduced by Thermal Research, highlighting their long-standing expertise in exhaust tuning.
