Check Vehicle Fit

These days, the DIY or do-it-yourself crowd is all about creating custom work and one-off exhausts are no exception. Whether you're working on a classic car, race car or just your daily driver, a MagnaFlow universal converter should be the standard building block for your custom exhaust. Since these items are universal, some modifications may be involved such as cutting or welding.
