Universal catalytic converters aren't cut to any particular vehicle; instead they're supplied as a straight-through unit that an exhaust fitter cuts and welds into an existing or custom-built system. They're the standard choice for fabricators, modified vehicles, and anyone replacing a cat where a direct-fit option isn't available. Our range spans multiple cell counts and pipe diameters, so you can match the unit to your priorities — a 400 cell catalytic converter for tighter emissions compliance, or a 100 cell catalytic converter where flow matters more. If your vehicle has a factory-shaped cat that bolts straight in, our standard replacement converters range may be a simpler option.

What's the difference between a universal and a direct-fit catalytic converter?

A universal converter has no vehicle-specific pipe ends or mounting points and needs cutting and welding into place, while a direct-fit (standard replacement) converter bolts straight into an OEM exhaust system.

What cell count should I choose for a universal catalytic converter?

It depends on the goal: choose a 400 cell unit for emissions compliance and roadworthy inspections, or a 100 or 200 cell unit for less restriction on performance-focused builds.

Can I fit a universal catalytic converter myself?

It requires cutting and welding into your existing exhaust, so it's best handled by a qualified exhaust fitter to guarantee a leak-free, roadworthy-compliant result.

Will a universal catalytic converter trigger a check engine light?

Incorrect fitment, wrong orientation, or a mismatched cell count relative to your engine can trigger oxygen sensor fault codes, so correct positioning and cell density are important.
