Overview
The MagnaFlow 418005 is a universal catalytic converter, marked Universal Fit rather than matched to a vehicle list. A catalytic converter is the emissions part in the exhaust that treats engine gases, and this stainless steel unit uses a monolithic honeycomb catalyst. The title names it a universal California converter.
The converter has a ribbed body with funneled inlets and outlets, a stainless steel body and heat shield, and a flow efficient honeycomb catalyst designed for maximum flow and surface area. It is built to EPA guidelines for 49-state use. Check your state’s emissions rules before fitting it.
Key features
- Universal Fit, not limited to one vehicle list
- Ribbed design with funneled inlets and outlets
- Stainless steel body and heat shield
- Monolithic honeycomb catalyst designed for maximum flow and surface area
- MagnaFlow states its 49-state converters comply with EPA guidelines
Matching a universal converter
A universal converter is sized by measurement rather than by a vehicle chart, so the fit comes from checking your own exhaust. Start with the pipe diameter at each end of the converter position, then measure the overall length the space allows. A stainless steel body and heat shield help resist corrosion over time. The honeycomb catalyst does the emissions work, so the converter should be installed in the same orientation as the original.
Mounting points matter as much as size. Compare hanger positions and bracket locations with the original pipe so the converter does not sit under strain. A converter forced into place can crack its joints or loosen its clamps. After installation, check each joint for exhaust leaks and look for contact with the body or frame.
- Measure pipe diameter at both ends
- Match hanger and bracket positions
- Check clearance from the body and frame

Vehicle fitment
It is marked Universal Fit and is not vehicle-specific. Sizing and mounting are the main checks. Confirm the inlet, outlet and length against your exhaust before ordering, and confirm your vehicle’s year, model and trim.
Confirm the converter’s size and mounting against your own exhaust, and confirm your vehicle’s year, model and trim before ordering.
Installation notes
Fitting this universal converter may involve matching pipe diameter and mounting points, and welding or cutting may be needed. Plan the fit before you rely on it.
