Borla Cat-Back Exhaust Install - Adding Bark To The Bite
Add Power And Great Sound With A Borla Performance Cat-Back Install
A BBK cold-air intake was installed that likely added a few horses without any negative repercussions. Another common project known to add power and presence is an exhaust-system upgrade. It was that modern muscle sound that sold Woods on the first Ford in his family, so he was originally reluctant to change the familiar notes he knew and loved. He decided on a Borla Performance Cat-Back system after hearing a number of recommendations and personal confessions about the company. A quick perusal online proved that the company did indeed manufacture a system for the '04 4.6 V-8 Mustang GT. A phone call later, and a big box from Borla was on its way.
Having some automotive know-how but not owning a hoist or dyno, Woods went to SG Motorsport to have the system installed. The local shop had a good reputation for being honest and affordable, which is often hard to come by in this industry. Owner Sasha Anis personally worked on this project, as he previously had little experience with Mustangs. "I mostly work with sport compacts, but I love getting the chance to work on different cars," he says.
The first thing Anis did, of course, was strap the Mustang to his Dynapack dynamometer for a baseline reading to see what kind of numbers the car was currently putting to the tire, so we could measure the Borla system's improvement. After warming up the car and running through a few good pulls, Anis was satisfied with the initial reading of 218 hp and 238 lb-ft of torque at the rear wheels. With a baseline established, it was off to the shop lift for the actual R&R work.
