The BLOX Racing 4.0-inch 2-bolt exhaust gasket is sized for 4" two-bolt flange connections as a direct replacement seal. It renews the flange joint to help prevent exhaust leaks and maintain proper exhaust routing and sound control. Intended for technicians and DIYers working on larger-diameter exhausts, it matches the 2-bolt pattern and 4" pipe size for correct installation and reliable sealing.
