This part cross-references AP Exhaust TNS3.328G2EK for the same application.

What It Helps Address

• Failed or inefficient catalytic converter performance
• California emissions compliance concerns
• Exhaust restriction from a worn or damaged converter
• Check engine light conditions related to converter efficiency
• Fitment issues from non-direct replacement exhaust parts

Installation Notes and Tips

Verify the vehicle year, make, model, and left-side/front-left position before installation. This converter uses welded flanges and does not include O2 sensor ports, so confirm the existing exhaust configuration matches the part. Because this is a CARB-compliant application, confirm the Executive Order number D-280-101 matches your vehicle and emissions requirements before service.

Quality Assurance

AP Exhaust states that this converter is manufactured to exact OE dimensions using automated workstations, spinner welding equipment, and high-speed production lines for consistent fitment and build quality. The product is identified with California Executive Order D-280-101.
