Like most everything Magnaflow sells, the Off-Road X-Pipe is made from 100% stainless steel. In this case, it's mandrel bent 3-inch stainless steel tubing that is designed, dyno tested and proven to make power for your Mustang. This particular off-road X-pipe is designed for the stock manifold or shorty headers. In our Mustang, we're intending to keep the headers the same or, perhaps, add aftermarket shorty headers, so this X-pipe is a going to be a perfect fit. If you're looking to add long tube headers, though, Magnaflow has numerous H-pipes or X-pipes that would be perfect upgrades for those situations.
Please note: This X-pipe from Magnaflow does NOT include catalytic converters, so it's not going to be legal for use on public roads or highways. Keep it off-road!
Installation of the Magnaflow Off-Road X-Pipe is a pretty simple process. The most difficult step is going to be accessing the bolts where the factory H-pipe and new X-pipe attach to the headers. While most of them can be reached from underneath the car, it's much easier to snag every extension in your toolbox and reach the top-right one from above. From there, the old parts just slide off and the new ones go in. The whole process only takes a little over an hour for the average installer.
One of the most convenient features of this Magnaflow product is that it comes in three pieces, with all of the hardware included. With the confined area near the header, it can be very difficult to get both ends of the X-pipe to perfectly line up, so Magnaflow breaks it into three pieces, with two separate, short pipes that go from the headers to an area underneath your Mustang GT, where it's much easier to attach and line-up the X-pipe itself. As Bill demonstrated in the video, it's also much easier to install when you get a friend to help you line things up.
While we haven't had our 2011 Ford Mustang GT dyno'd to see how much power we picked up with these upgrades, we sure do like the sound that our Magnaflow Cat-Back System and Magnaflow X-Pipe produce together. Since it belongs to a team member here at CJ's, we love hearing it coming in and out of the parking lot, and he's extremely happy with his new system from Magnaflow.
The upgrades aren't stopping here! Keep checking our YouTube channel and blog for the latest updates on our Mustang project cars, our 2013 Ford F-150 EcoBoost and our 2014 Ford Focus ST. We're always busy working on them and will continue to bring you our experiences with upgrading, adding the latest parts on the market and showing you how they fare on the dyno!
