[ Note ]
Fitting RRP High Performance Silence Center Pipe makes the noise of exhaust in silent but please confirm to measure the noise by yourself after fitting to match your local inspections.
We have designed and developed RRP High Performance Silence Center Pipe aiming power up and silence both.
The current center pipe is a expanding pipe type which makes a large noise but RRP High Performance Silence Center Pipe is controlling the exhaust noise in low and power up effect.
Especially if you feel the exhaust sound has being increased by fitting catalytic manifold, center pipe and muffler, or you worry about the inspection per a year, you recommend you our RRP High Performance Silence Center Pipe for your car.
Testing result of the noise at R's Inc
