The factory o2 housing on the 1.4 turbo Ecotec motor has been shown to be quite restrictive. Our 2.5" Stainless steel high-flow version has been dyno proven to produce gains of up to 8 horsepower at the wheels. This is a gain of more than 6 percent! This easy bolt-on modification re-uses the factory V-band clamp where it attaches to the turbo. Comes with everything needed to install just replacement bolts and nuts. Dec 2014: It comes with 2 o2 bungs, and a plug in case you want to add a wideband o2 sensor later. 

Note: This O2 housing does not include a catalytic converter, we move the cat to our mid pipe if you have a Cruze, if you do not install our midpipe or 2nd cat section with this product it will set check engine light without ECU programming. If you have a Sonic, you will require tuning to not set a check engine light. 

For a complete street setup that does not require ECU programming, see our O2 housing/mid pipe combo. This part fits the 1.4 Chevy Sonic, Cruze, and Buick Encore.

We recommend replacing the v-band clamp while installing the O2 housing since they are a common failure point. 

Installed on Cruze sound clip


Verified fitment on 1.4L Turbo Vanderhall Venice. 

Updated 8.25.2020 to no bracket and includes flex section. 

We are currently offering $60 in store credit to purchase your stock catalytic converter back from you (only the primary cat on the 1.4, not the mid-pipe). If you're interested, take a photo of your stock downpipe and email it to Henry@zzperformance.com. We will provide prepaid shipping labels for domestic (U.S.) shipments.

Zzp downpipe

Really easy to install only took me and my brother 30 mins. Really enhances your Turbo sound. Will set off check engine light but I will be getting my Cruze tuned next week so that will eliminate the light. 10/10 would recommend

One of the first mods you should buy

Made the biggest difference in performance, the turbo spools much quicker and sounds amazing. Install was super quick and easy.

Love it

Part works beautifully! It sounds great when coupled with my Spectre cold air intake. I cannot wait to get the midpipe and tune to complete my setup.
