Thermal R&D B188-C188 Frontpipe-Back Exhaust — 2018-2022 Honda Accord Sport 1.5T
The Thermal R&D B188-C188 is a frontpipe-back exhaust system designed for the 2018 through 2022 Honda Accord Sport equipped with the 1.5L turbocharged engine. Built in Lancaster, California from T304 stainless steel, the B188-C188 replaces the factory exhaust from the turbo-side frontpipe all the way rearward. Thermal R&D's patented Helmholtz resonator technology is calibrated for the Accord 1.5T's exhaust pulse characteristics to eliminate the standing wave drone that is common with aftermarket exhaust on turbocharged four-cylinder applications. The result is a system that delivers a refined, sport exhaust note without fatiguing the occupants on daily commutes or highway trips.
The B188-C188 exits with polished stainless tips and installs bolt-on with no modifications to the vehicle.
