This Sound Composer Pipe Delete Kit blanks off the factory sound composer pipework.Increasingly on modern cars quieter cabins with better sound insulation mean you're not getting as much real engine noise through into the interior.To fix this, increasingly manufacturers are resorting to either electronic trickery or special pipework connecting the intake to the cabin.While this is fine if you like the noise being piped into the cabin, not everyone does.For this reason Mishimoto are offering this blanking kit.It replaces the pipework for the sound composer with a blanking plug.The kit includes a CNC aluminium blanking plug to replace the intake hose and a rubber cap to install onto the sound diaphragm.
