What is a resonator and what's the difference between a resonated and non-resonated exhaust system?
A.
A resonator is a chamber in the exhaust system that contains a specific volume of air which is designed to cancel out certain frequencies of sound (made by the engine) - making the exhaust noise quieter.
Therefore, a non-resonated exhaust system will give you extra performance and a louder exhaust note and the resonated system will give you extra performance without increasing the exhaust noise much.
