2015 Ford Mustang GT: New Music From New Exhaust

by Jason Kavanagh, Engineering Editor on August 31, 2015

When Ford created the 2015 Ford Mustang GT, they made it appeal to the widest audience possible. That includes normal, everyday people. People who want a cool car, sure, but also want to drive it daily and want it to be as civilized as possible.

Accordingly, we've observed that our long-term Mustang GT has a fairly muted exhaust note. That's fine for the aforementioned normal people and a well-considered decision by the Ford engineers. But we're not normal, and we've wanted to relish in the vocals of the GT's 5.0-liter Coyote V8 since pretty much the first week we bought the thing.

So we did something about it.

Perusing the Ford Racing catalog, we selected the Touring Cat-back Exhaust System, part number M-5200-M8TC. It's a 50-state legal exhaust that promises to let loose the thunder of the V8, so it's right up our alley.

This was purely about acoustics. A big part of the pony-car driving experience is about the sound. We didn't do this in the pursuit of performance gains, nor does Ford claim any performance gain for the Ford Racing catback. Bonus: the new catback sheds about 30 pounds compared to the stock one.

Installation is pretty easy, true. But we'll use any excuse to visit Galpin Auto Sports, who did the labor of swapping the catbacks.

Outside of the service bays, Galpin Auto Sports is a miniature car-guy playground. The customer cars in the front parking lot alone are worth the visit. We saw an old-school Hemi Charger waiting for some work. In their on-site museum was a Cobra 289, a vintage Shelby GT350, a GT500KR, a '60s Mazda Cosmo, an Aston Martin DB6, the crazy Galpin GTR1 and so much more.

Just a badass 1966 Bronco in LeMans-era GT40 livery, built by Galpin and hanging out in the GAS showroom, that's all.

The stock exhaust comes out with the removal of two band clamps and four exhaust hangers. The Ford Racing exhaust has two additional band clamps for packaging ease.

Those two additional band clamps make it possible to juuust squeeze the boxed-up Ford Racing catback into the Mustang's passenger compartment. It'll go in and out through the passenger door, but not the trunk.

The Ford Racing exhaust has revised mufflers manufactured by Borla.

It also omits the stock exhaust's big resonator just aft of the stock X-pipe.

Getting the Ford Racing catback's exhaust tips to exit precisely in the center of cutouts in the rear fascia required a few taps of The Persuader. No exhausts were harmed in the making of this photo.

A perfect fit.

And now it's time to make some noise.

We've got audio clips of before and after that we'll share in a follow-up post. For now, you'll just have to make vroom-vroom sounds while viewing the photos here (additional photos in the gallery above).
