Product Details

Eastern Convertors Part Number 41031 is engineered for vehicles that require a direct replacement catalytic converter with factory-style fitment. The DIRECT FIT product line focuses on OE dimensions and consistent installation geometry, while the manufacturing process uses automated workstations, spinner welding equipment, and high-speed production lines to maintain dimensional accuracy. This converter is built for front or center undercar placement depending on application, and it is listed for 2015-2018 Audi Q3 front, 2015-2018 Audi Q3 Quattro front, 2017-2018 Volkswagen Tiguan Limited center, and 2009-2017 Volkswagen Tiguan center. This part cross-references no additional part numbers in the provided data.

What It Helps Address

• Failed or inefficient catalytic converter operation
• Exhaust restriction caused by a worn internal substrate
• Check engine light concerns related to catalyst efficiency codes
• Exhaust odor from a deteriorated converter
• Fitment issues from non-direct replacement exhaust parts

Installation Notes

Verify the vehicle’s emissions configuration before ordering. This converter is not for sale or use in California, New York, and Maine for vehicles with CA emissions, and the 2009-2017 Volkswagen Tiguan listing is not for sale or use in California, Colorado, Maine, and New York for vehicles with CA emissions. Confirm the inlet is a 4-bolt welded connection and the outlet is 2.375" OD before installation. Use the listed O2 sensor ports and gasket count as reference points during exhaust service.

Quality Assurance

Eastern Convertors uses advanced manufacturing methods to build converters to exact OE dimensions and fitment. The NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance across the listed applications.
