JDM EK4 Civic SiR B-Pipe Exhaust Section. B-Pipe is in great used condition, with only minor surface rust. The OEM Honda Civic EK4 SiR B-pipe features a 57.2 mm outer diameter, a 50 mm inner diameter, a built-in resonator, and an 8.8 kg weight, which provides a wider flow path and larger resonator compared to the smaller 45 mm outer diameter found on standard, non-VTEC Civic models. JDM B-Pipe is slightly longer than USDM mid pipe. Actual pictures shown.
