HTR Performance Exhaust System Mufflers are engineered as an acoustic soundproofing device designed to reduce the loudness of the sound pressure created by the engine by way of Acoustic quieting. The majority of the sound pressure produced by the engine is emanated out of the vehicle using the same piping used by the silent exhaust gases absorbed by a series of passages and chambers lined with roving fiberglass insulation and resonating chambers harmonically tuned to cause destructive interference wherein opposite sound waves cancel each other out. Made from the highest quality materials to withstand the tortures of everyday use.
