With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment.

Penelope U. ★★★★★

First time I've swapped a cat on an older car and the check engine light stayed off right from the start. The mandrel-bent tubing made installation a breeze, I didn't have to fight with any awkward angles or alignment.

Emma L. ★★★★★

Installed this on my 2016 Mustang and the check engine light finally turned off after months of frustration. The mandrel-bent tubing seems really solid and it bolted up perfectly.

Sofia D. ★★★★☆

The mandrel-bent tubing made installation smoother than I expected on my 2017 Mustang, and so far no check engine light issues. Fitment was spot-on with the factory mounts, though the welds could be a bit cleaner for the price.
