Different slip in silencers tested to get the sound below 95 db. They restrict the flow but do make the exhaust California legal with the silencer installed. With the silencer out, the car is quite loud on a drive by at WOT but inside the car is not bad. The silencer that is supplied with the system is easy to install and remove. | ||||||||||||
