Product Details

When it's time to replace the catalytic converter on your 1999-2005 Mazda Miata, this MagnaFlow HM Grade unit is a solid option. It's designed to meet Federal emissions requirements, helping you keep that check engine light off and your car running cleanly. You'll get the converter itself, along with the necessary hardware like flat washers, nuts, bolts, and a flat ring gasket, making the installation process more straightforward.

This converter is built with 16-gauge 409 stainless steel tubing, which is known for resisting corrosion and ensuring a long service life. The tubing is mandrel-bent to maintain the original flow dynamics, so you shouldn't see any significant drop in performance or fuel efficiency compared to the factory part. MagnaFlow uses 3D scanning during their design process to ensure this converter fits and functions just like the original equipment, and the single laser fusion weld is designed to minimize the chance of exhaust leaks. Its compact, low-mass design also contributes to better thermal efficiency.

This is a direct-fit unit, meaning it's designed to bolt up to your existing exhaust system without needing any cutting or welding, provided you have the proper tools for installation. Just remember that this converter is EPA-compliant and not approved for sale or use in California due to emissions regulations.
