Product Details

The AP Exhaust 1TYXT02.4FFP product line is built around OE-style fitment and manufacturing consistency. AP Emissions Technologies uses advanced production methods and substrate chemistry to produce converters with efficient catalyst loading and exact dimensional control, helping maintain proper exhaust flow and emissions performance. This AP Exhaust catalytic converter manifold is made for the front position on Toyota Highlander models and is listed for California emissions compliance under EO D-280-101. The part number 912532 is the correct reference for this application.

Fits 2001 Toyota Highlander, front. Fits 2002 Toyota Highlander, front. Fits 2003 Toyota Highlander, front. This part cross-references AirTek, Inc. (e.g., D-280-101) for the same application.

Common Issues This Part Can Address

• Failed catalytic converter efficiency codes
• Exhaust leaks at the manifold connection points
• Emissions test failure related to converter performance
• Restricted exhaust flow from a deteriorated converter
• Fitment problems caused by non-direct-fit replacement parts

Installation Notes and Tips

Verify the front-position application and confirm the 5-bolt inlet and 2-bolt outlet flange configuration before installation. Check all mating surfaces, sensors, and exhaust connections for wear or damage so the new converter manifold seals correctly. Because this is a CARB-compliant direct-fit manifold, it should be matched to the exact vehicle year and emissions requirement listed for the Toyota Highlander.

Quality Assurance

AP Exhaust builds this converter manifold to exact OE dimensions using automated manufacturing and high-speed production processes for consistent fitment and repeatable quality. The unit carries Executive Order D-280-101 for the listed California-compliant applications.
