ATLP High-Flow Metal Cat, 2009-14 Acura TL Base FWD, ES0009HF



The ATLP High-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. Tapered design also increases overall volume over the factory unit.

The ATLP High FLow Metal Cat also allows the use of the factory heat shield to retain a factory look and keep the cat protected.

Your vehicle is not be equipped with traditional "headers." Before going further, we would suggest reading this article regarding the exhaust layout on your J-Series Engine equipped vehicle: An Outline Of The Exhaust Layout On J-Series Honda V6 Engines

We can provide a complete set of exhaust components from the engine to the tips, and will be happy to consult you on the needed items.

  • Heat Shield fitment January, 6
    By Chris, Street Performance Enthusiast
    The hi flo cat fits perfectly with the atlp j-pipe and stock exhaust pipes after the cat. Sound is slightly noticeable. Reinstalling the heat shield for me had issues. 2 holes were flush with the cats mounts but the other 2 were off by 1/2inch. I sent in pictures to support@heeltoeauto but have yet to receive a reply. Despite the heat shield mounts(i probably just gote one that was off, it happens) it's a very solid product!!! Definitely will buy more products from here!
    Please make sure pictures sent in are smaller than 1Mb or we will not get them!, Heeltoe
