ZZ LTG O2 Housing w/ Catalytic Converter

The ZZPerformance ZZ LTG Malibu/Regal O2 Housing is engineered to directly connect the turbocharger's outlet to the factory downpipe. This 3-inch diameter, 100% stainless steel component offers an integrated bung for your factory O2 sensor, ensuring seamless integration. The outlet flange is tapped to match the factory O2 housing, simplifying installation by eliminating the need to hold bolts in the confined engine bay. This O2 housing incorporates a ZZP 400-cell high-flow catalytic converter, as the company does not offer catless products. Our high-flow catalytic converters are EPA certified. However, please note that these do not meet CARB compliance standards if your state requires it. Fitment is specific: This O2 housing fits 2.0L LTG engines only and will not work with the 1.5L engine. It is incompatible with '18 and up Regals due to a change in their exit flange design. While it fits various '13-'17 Malibus and Regals, ensure you select the correct model, as '13-'15 Malibus and '14-'17 Regals use a 3-bolt flange, while '16+ Malibus feature a 2-bolt exit flange. This product also does not fit rear-wheel-drive LTG ATS, CTS, or Camaro models.
