This 3 inch Competition Series cat-back exhaust from MagnaFlow features a 2.5 inch inlet that allows you to connect it to your factory exhaust system. The system then expands to 3 inches to provide better exhaust flow. If you are looking to connect the system to your 3 inch header tube, cutting and fabrication will be required to adapt the inlet.

Intense sound. The MagnaFlow cat-back exhaust gives your Mustang the powerful sound that you crave. Don't hide the impressive sound of your V8 engine, announce your presence with this Competition Series cat-back. The system will provide a menacing sound with a deep rumble at idle and an intimidating acceleration.

Increase performance. The 3 inch mandrel-bent tubing provides smooth exhaust flow and will not restrict the engine when you add power adders or modify your New Edge. MagnaFlow's mufflers feature a straight-through design that will not restrict exhaust flow.
