About the Part NumberGive your fierce muscle car something to growl about when you replace its wimpy stock pipes with new BBK Off Road Cat Delete Exhaust Pipes. This new part number is custom-fit for your 2011-2013 Ford Mustang 5.0L to deliver more horsepower. These CNC mandrel-bent aluminized pipes measure 2.5” in diameter and are merged in a unique “X” section to maximize air flow.
Plus, since BBK designed this part for your Mustang, it installs easily without drilling. It simply bolts on with the included hardware. And, when you purchase your new off road pipes from AutoAnything, we ship them for free and back them with our 1-year lower price guarantee. So, if you find BBK part number 1674 anywhere else for less, we refund the difference and beat it by a dollar. What’s more, these pipes are backed by BBK’s 1-year warranty.
