RRP High Performance Silent Center Pipe For Suzuki Swift ZC31

Car Make: Suzuki
Model: ZC31S

A catalyst-less center pipe that achieves a quiet volume while aiming to improve power.
Until now, there were cases where the volume of the center pipe increased with the expansion pipe, but the silent center pipe improves the power while suppressing the volume.
It is ideal for those who inevitably raise the volume too much or who are concerned about the volume due to the combination of a catalyzer, center pipe, muffler, etc.
