  • Easy Installation

The standard OE specification flanges are designed for easy installation. Bolt-on connection, flange to flange, direct installing to existing exhaust system without doing the extra modification.

  • Durable & Long-lasting

Features stainless steel outer shell construction for maximum durability. The internal substrates and precious metal loading have been carefully engineered for maximum efficiency and to avoid MIL code issues.

  • High Flow Cats Increase Power

Internal honeycomb structure for maximum flow and surface area. Allows the catalysis to fully react with exhaust gases without sacrificing flow rate, thus reducing the backpressure. The increased exhaust flow allows your engine to make more power, improve vehicle performance.

  • Eliminate P042 Code Error

This catalytic converter can eliminate the “check engine light” caused by code P0420 (catalyst system efficiency below threshold). Before replacing a catalytic converter, please make sure your O2 sensors function properly. Faulty sensors can cause damage to spark plugs, catalytic converters, and damage your fuel economy.
