New car reviewers put a lot into discussing the way a car sounds. For us, how the car sounds is really just a baseline. There’s no need to get that worked up about the stock sound, as we can promise it will almost always be too quiet.
Right there with us is the crew at Latemodel Restoration. They didn’t wait long to put the company’s Triple Yellow Mustang GT under the modding knife. After installing a set of DF5 wheels, they got down to the power mods with a full cat-back exhaust from Gibson Performance Exhaust.
“The complete, dual, 3-inch, stainless steel X-pipe and trusted, power-proven SuperFlow mufflers with integrated CFT technology will create symphony under the chassis, as they work in tune to push any driver deeper into their seat,” Gibson enthused. “With each rap of the throttle, the throaty sound exiting from the dual, 4.5-inch, intercooled stainless tips will work to alter their ego from Office Clerk to Road Warrior.”
If you’d like to hear the system, you can listen right here:
While the sound is obviously a really important part of an exhaust upgrade, the Latemodel Restoration team loves adding power too. As such, they baselined the car on the company’s in-house dyno before installing the Gibson system and testing it again. Here’s the video proof:
“This 2015 Mustang Gibson cat-back exhaust kit not only gives you a great horsepower increase, it also adds a throaty exhaust tone,” says Latemodel Restoration. “It features an X-pipe and Superflow mufflers to help get maximum performance. It is finished off with 4.5-inch, black intercooled tips to give the rear of your S550 a stealthy new look.”
If you are interested in the upgrade, we thought we’d bring you a few highlights of the installation, as well as the before-and-after dyno graphs.
