Frequently Asked Questions

Will a Magnaflow catalytic converter increase my horsepower?

Yes, slightly. Magnaflow high-flow catalytic converters have lower restriction than OEM units, which can free up 5-15 horsepower depending on the application. The biggest gains are on V8 and turbocharged engines. Naturally aspirated 4-cylinders see smaller gains.

Will a Magnaflow CARB catalytic converter pass smog in California?

Yes, if you select a Magnaflow CARB-compliant version with a valid CARB Executive Order (EO) number. Federal EPA-only Magnaflow converters will fail California smog inspection.

Does Magnaflow change my exhaust note?

Catalytic converters do affect exhaust tone, but the change is subtle. Magnaflow units typically produce a slightly deeper, more aggressive sound than OEM. For dramatic sound changes, pair the catalytic converter with a Magnaflow performance muffler.

Are Magnaflow universal catalytic converters legal in California?

Universal catalytic converters are NOT legal in California. CARB states require direct fit catalytic converters with valid EO numbers. Magnaflow universal converters are only legal in non-CARB states.

What is the warranty on Magnaflow catalytic converters?

Magnaflow offers a 5-year or 50,000 mile limited warranty on their catalytic converters covering manufacturing defects and emissions performance. The warranty does not cover damage from contamination, engine problems, or improper installation.

Do you ship Magnaflow catalytic converters nationwide?

Yes. We ship Magnaflow converters to all 50 US states. Shipping cost is calculated at checkout based on package dimensions and destination.
