"quality of product great price and fast shipping!!!" posted by: ray on June 25, 2014

"This converter appears to be well built, and solved my P0240 (inefficient catalytic converter) code problem immediately. Can't beat the price and free, quick (3 days) shipping. If your existing front pipe is in good shape, this converter is well worth the hassle of adapting it to fit." posted by: Pistole on September 11, 2010 view all 5 reviews

Your Ford Mustang can be considered as an air pollutant machine if it is not equipped with a reliable catalytic converter. Vehicle exhaust emissions are packed with lethal gases that are extremely harmful to the environment. Without a properly working Ford Mustang catalytic converter, these noxious fumes will be released into the air and cause major pollution. To make your Ford Mustang more eco-friendly, you must install an efficient catalytic converter that can effectively transform the deadly exhaust emissions into less harmful forms of gases. Damaged or malfunctioning catalytic converters must be replaced immediately to avoid violating your local emissions law.

Frequently Asked Questions

Ask APW
  • Is it legal to replace the stock Ford Mustang catalytic converter with an aftermarket unit even if it is still in good working condition?
    Answer: No. Federal regulations prohibit the replacement of a stock catalytic converter unless it is damaged or defective. A state or local inspection program must first check the condition of the catalytic converter to determine whether it needs replacement. If the inspection results show that the catalytic converter is still in proper operating condition, then the driver has no choice but to stick with the stock unit. It is also illegal in some states to remove the catalytic converter, and vehicle owners caught violating this law will be heavily fined.
  • Should the stock Ford Mustang catalytic converter be replaced with a high-flow unit to gain better power output?
    Answer: High-flow Ford Mustang catalytic converters are designed to improve the vehicle's exhaust flow and increase the engine's horsepower. The increase in horsepower percentage and torque is very minimal though, especially when there are no other modifications made to the engine. To achieve better power output, the stock exhaust system should also be upgraded and modified so that it will work well with the high-flow catalytic converter. Before installing a Ford Mustang catalytic converter replacement, make sure its design complies with local state requirements to avoid any legal violations.
  • When should the Ford Mustang catalytic converter be replaced?
    Answer: For 1996 or older Ford Mustang models, the catalytic converter should be replaced once it reaches more than 50,000 miles of operation on the odometer. The vehicle must first be taken to a certified automotive shop to verify the need for replacement before the owner can install a new unit. For newer Ford Mustang models, the stock catalytic converter must only be removed and replaced after the eight-year or 80,000-mile warranty has expired to comply with the legal OBD-II (On-board Diagnostics, Part Two) regulations.
