Forced Performance Mitsubishi Evo 9 Cast O2 Housing Assembly (w/o Dump Tube)

What you get with this Forced Performance O2 Housing Assembly is a well-built cast iron piece designed to replace the stock housing on your Mitsubishi Evo 9. This assembly is specifically made without a dump tube, which is a configuration some tuners prefer for certain setups. It's a direct replacement part, meaning it's made to bolt up to your existing turbocharger and exhaust system.

This cast O2 housing is a popular choice for Evo 9 owners looking to improve the exhaust flow right out of the turbocharger. By smoothing out the transition from the turbo's turbine outlet to the downpipe, it can help reduce backpressure and allow the turbo to spool a bit more freely. The cast iron construction is solid and durable, intended to handle the heat and pressure of a performance turbo setup. It's a straightforward upgrade that can make a noticeable difference in how your turbo performs.

Keep in mind that this part is not CARB approved and cannot be shipped to California. If you're building a performance Evo 9 and want to optimize your turbo's exhaust side, this O2 housing is a solid option.
