Detailed Product Description

This AP Exhaust catalytic converter with integrated exhaust manifold (part number 641298) is specifically designed to fit Lexus and Toyota models including the Highlander, RAV4, RX350, RX450h, and Sienna. The stainless steel construction provides resistance to rust and corrosion, extending the life of the exhaust system. The ceramic substrate inside the converter efficiently reduces harmful emissions by facilitating chemical reactions that convert exhaust gases into less harmful substances.

The inlet side features a 6 bolt welded flange for a secure connection, while the outlet side uses a 2 bolt welded flange with a bent bracket to ensure proper alignment and fit. The inclusion of one O2 sensor port allows for accurate oxygen sensor placement, which is critical for engine management and emissions control. Both inlet and outlet gaskets are included to help maintain a tight seal and prevent exhaust leaks.
