Alta Performance AMP-EXT-050 Alta Header Systems

Dont overspend when replacing the OEM catalytic converter! The ALTA Performance Cooper replacement catalytic converter with header is a great option for those needing to replace their non-functioning, or out of warranty converter. Important details about when you can legally replace your catalytic converter can be found here.

ALTA replacement catalytic converter includes the proper approval for use in all states that do not require CARB approval. We also include a 5 year / 50,000 mile warranty. This high-quality converter combined with the ALTA header make for a great alternative to spending too much for a new OEM part.

The header portion of the catalytic converter replacement is a 4-to-1 design similar to the OEM header. This allows for the OEM heat shield to be installed keeping the excess heat from entering the engine bay, and possibly your intake system. The header uses 1.5 tubing, and 11 long primaries, before making it to the collector. The rest of the piping is 2.5 to match your 2.5 exhaust system.

These features make the ALTA Performance catalyst replacement a legal option (see notes on catalyst replacement prior to ordering specific to your state, not legal for use or sale in California), a better looking option, and a less expensive option, for those in need of a replacement catalytic converter.
