Compact Catalytic Converter for 5.0L V8 Mustang

If you're running a 2015–2020 Mustang GT and you're starting to notice sluggish throttle response, a persistent check engine light, or maybe your exhaust just doesn’t sound right anymore, your catalytic converter might be trying to tell you something. Whether you're dealing with a failing stock unit or you're building a compliant street car in a CARB-regulated state, the MagnaFlow CARB Compliant Manifold Catalytic Converter is the kind of replacement that doesn’t just meet legal standards; it does it with performance and longevity in mind. This isn’t your average universal cat. It’s a manifold-style direct-fit converter designed specifically for the 5.0L Coyote V8. That means it bolts directly into place where your factory exhaust manifold and catalytic converter assembly sits, eliminating the guesswork. There’s no cutting, no welding, and no worrying about alignment or clearances–it fits like OEM because it was engineered using precise 3D scanning of the original factory parts. Everything from the O2 sensor port placement to the flared connections is designed to match up exactly with your existing system.

CARB Compliant Design

What really sets this piece apart, though, is the CARB compliance. If you live in California or another state that follows CARB regulations, you already know how strict those emissions rules are. MagnaFlow took the extra step to ensure this converter meets all those requirements, including the more rigorous certification and testing needed for legal use in CARB states. It's a legal, worry-free solution that keeps your Mustang on the road and off the radar of emissions inspectors.

Premium Build Quality With Straightforward Install

As for the build itself, MagnaFlow doesn’t mess around. The converter features a spun stainless steel body that’s not only more resistant to corrosion and cracking than stamped designs, but also more compact and efficient in managing heat. A single laser fusion weld holds the whole body together, reducing potential leak points while giving it the structural strength it needs to handle everyday abuse. Inside, the mandrel-bent tubing helps keep exhaust flow smooth and unrestricted, so you're not sacrificing performance just to stay compliant. Installation is as straightforward as it gets. The converter ships with the gaskets and hardware you need, so you won’t be stuck trying to salvage rusty bolts or digging through bins at the parts store. With a basic set of tools and a little bit of time, you can get the old unit off and the new one installed in your own garage.
