This product is a genuine Linhai exhaust pipe gasket kit, part numbers 23403 / 170M.19.3, specification 30/40×5mm. This gasket is installed between the exhaust pipe and engine exhaust port, providing a seal to prevent high-temperature exhaust gas leakage, ensuring proper exhaust system operation while reducing exhaust noise and protecting engine performance.

The exhaust pipe gasket is a wear-and-tear part. Over time, it may experience aging, burning, deformation, or damage, leading to exhaust leakage, unusual noise, and power loss. Timely replacement of damaged gaskets is essential for maintaining exhaust system sealing and restoring engine performance.
