HKS MTL CAT Nissan Universal Oval

This is the HKS MTL CAT Universal Oval Catalytic Converter, designed for custom exhaust applications where a direct-fit replacement isn't available. It's built to help your Nissan meet emissions standards by converting harmful exhaust gases into less harmful ones. Because it's a universal part, it requires custom fabrication and welding to integrate into your existing exhaust system, making it a solid choice for enthusiasts building a unique exhaust setup.

The core of this catalytic converter is constructed with a durable metal substrate, which is known for its ability to withstand high temperatures and vibrations common in exhaust systems. This metal construction offers improved durability and faster light-off times compared to traditional ceramic substrates, meaning it starts working to clean your exhaust gases sooner after startup. The oval shape allows for a more compact installation in tighter spaces, which can be crucial when fitting a custom exhaust system. It's important to note that this converter is not CARB approved and cannot be shipped to California due to emissions regulations.

When planning your installation, remember that this is a universal component. You'll need to have the necessary welding and fabrication skills, or work with a professional exhaust shop, to properly install it. Ensure you have all the required exhaust piping, hangers, and clamps to complete the custom setup. This part is intended for off-road or competition use where emissions compliance is handled differently, or for vehicles where a custom solution is the only option to meet local regulations.
