Aeroflow's copper embossed exhaust gaskets are the perfect choice for high performance engines, especially those supercharged or turbocharged where the exhaust is pressurized and leaks are common. The solid copper design will not shrink or deteriorate causing a potential blow out and exhaust leak. Designed with a crimp collar which outperforms other gaskets because of its sealing bead that conforms to the flange sealing surfaces and provides a leak free seal. Available for applications ranging from specialized racing engines to OEM replacement to suit various makes and models.
