LTG O2 Housing

The ZZP LTG Malibu/Regal O2 Housing is designed to bolt directly to your vehicle's turbo outlet and connect to the factory downpipe. This exhaust component measures 3 inches in diameter and includes a bung for the factory O2 sensor. Constructed entirely from stainless steel, it features a tapped outlet flange for simplified installation, eliminating the need to hold bolts in tight engine bays. This O2 housing integrates a 400-cell high-flow catalytic converter and is EPA certified. ZZP does not offer catless products. Included hardware consists of three M8x30mm bolts and an O2 gasket. Careful selection of the correct model is crucial for proper fitment. The '13-'15 Malibu and '14-'17 Regal models utilize a 3-bolt exit flange, while the '16+ Malibu models feature a 2-bolt exit flange. It is important to note that this O2 housing does not fit '18 and newer Regals due to their switch to a 2-bolt exit flange. Additionally, this product is exclusively for the 2.0L engine and will not fit the 1.5L engine. It is also not compatible with rear-wheel-drive LTG ATS, CTS, or Camaro models. Customers should be aware that while the high-flow catalytic converters are EPA certified, they do not meet CARB compliance standards for states requiring it. For questions regarding compliance or specific fitment, contacting ZZPerformance customer service is recommended.
