Product Description
The 3rd cat on the TL was designed to be used with the stock exhaust system and stock J-Pipe. When upgrading to an aftermarket exhaust system, the larger piping diameter is still limited by the factory 3rd cat, which has a 2.25” diameter that causes a restriction on exhaust flow, and subsequently limits exhaust performance gains.
The ATLP Hi-Flow 3rd Cat utilizes a high flow/high volume 200-cell metallic catalyst that is a direct OE replacement. It features an ultra- smooth tapered design to retain maximum velocity through the entire converter. The cross section is also increased by 12% over OE to a 2.5” diameter. The design of the cats also allows the use of the factory heat shield to retain a factory look and keep the cat protected.
