Ford is definitely on the right track with the fresh design of the 2015 Mustang. Rather than just preaching to the choir, the company sought to convert new Mustang enthusiasts with the modern styling and technology found in the latest pony car. That combo swayed Richard Sarver and his son Colby into choosing a new Mustang GT for a father/son project rather than a Suburu WRX. Nice choice, fellas!
After ordering a Magnetic GT, they instead scooped up a Triple Yellow version that was in stock at a local dealer. Once you have a project car in hand, the next move is planning those mods, and the father and son team were soon eyeballing possible exhaust upgrades to give the GT some much needed bark.
“Colby knew that he didn’t want his car to remain stock for long, so they enlisted the help of Pro Dyno to find the right exhaust setup for it,” Jeremy Marler, Marketing & Social Media Manager, at Pro Dyno, said. “Richard and Colby had seen (and heard) that Stainless Works was working diligently on the new S550 exhaust systems and that is what they wanted!”
As luck would have it, Pro Dyno was on the list to get one of the first production Stainless Works systems for the S550 GT. When it arrived, the Pro Dyno team got to work on the pristine new GT. The removed the stock exhaust, added a JLT Performance cold-air intake, and Pro Dyno main man Dan Desio worked his tuning magic to make the computer work with all the new parts and maximize their benefits.
“I just used the fundamentals that I used on the ’11-’14 cars, you just have twice the number of tables… Ford pretty much doubled all the tables—torque tables, variable cam timing tables, etc.” Dan explained. “They just added more ability for the computer to learn more, which should help the driveability.”
To get an idea how the car sounds with the new Stainless Works system, you can watch the Sarvers’ GT run on the Dynojet at Pro Dyno and on the street right here:
Clearly the results of opening up the intake and exhaust on the latest Mustang show that it still responds to the tried-and-true hot-rodding techniques just like its predecessors.
“Once the tuning was finished, it was a different car. It was night and day. Where you didn’t see it in the graph—the driveability—it was a different car,” Dan enthused. “From First through Third gear at about ¾ throttle it will break the tires loose without even trying to break the tires loose.”
