Thermal R&D Frontpipe-Back Exhaust System – 2018-2022 Honda Accord Sport 1.5T & 2.0T
The Thermal R&D B188-C188 Frontpipe-Back Exhaust System is a high-performance cat-back upgrade designed specifically for the 2018-2022 Honda Accord Sport with the 1.5T and 2.0T turbocharged engines.
This dual exhaust system starts with 2.5″ tubing that splits to 2.25″ tailpipes, delivering improved exhaust flow, reduced backpressure, and a noticeably more aggressive acceleration sound while remaining drone-free in the cabin during cruising.
Engineered to fit perfectly with the OEM valance and bumper, the system retains all factory hangers for a direct bolt-on installation. Constructed from premium T304 stainless steel, it features a mill finish on the front pipe, tubing, and resonator, paired with a brushed stainless muffler for a clean, sporty appearance.
An internal rear chamber utilizing Thermal R&D’s exclusive ‘True Helmholtz Technology’ (THT)™ effectively cancels drone at highway speeds while preserving the deep, throaty turbo growl under acceleration. This is the perfect exhaust upgrade for Accord Sport owners seeking better performance, sound, and style without compromising daily drivability.
