Stop the installation and contact Philtop customer support. Please provide your vehicle information, order number and photos of the original and received parts so we can help review the fitment.

Check for existing issues—exhaust leaks, engine warning lights, damaged sensors, or other engine problems. Correcting these first helps protect the replacement part. Check the product for damage—look for cracks, dents, bends, or broken welds from shipping. Contact us with photos if you find any. Compare with the original part—verify the shape, mounting position, flange type, pipe diameter, and sensor locations match to confirm fitment.

Please confirm the fault codes were cleared after installation, then have the vehicle scanned for trouble codes and check for other engine or exhaust-system issues—the converter may not be the only cause of the warning light.
