Show original supplier description
The XAT Racing Mk3 Supra High Flow Cat is a direct-replacement, bolt-in catalytic converter designed for the 1986.5 to 1992 Toyota Supra models equipped with either the 7MGE or 7MGTE engine. This unit features a 3-inch diameter and is crafted from stainless steel for durability. Installation is intended to be a direct replacement for the factory catalytic converter. Owners can expect an approximate 5% increase in power and a quicker turbo spool. It's important to note that this catalytic converter is 49-state legal, meaning it complies with emissions regulations in most of the United States, but it is explicitly not legal for use or sale in California due to emissions laws. This high-flow catalytic converter is made to order. Customers must measure their existing catalytic converter to determine if they require an 11-inch or 12-inch version before placing their order. Gaskets are not included with the purchase but are readily available from local auto parts stores or can be substituted with products like Permatex Ultra Copper. Hardware for installation is also available as an optional add-on. This product is manufactured in the USA. Due to emissions regulations, this catalytic converter cannot be shipped to a California address.
