News: 2015 Mustang Gibson Exhaust Dyno Run

Wondering how the aftermarket would handle the monolithic factory exhaust system? You can see Gibson picks up right after the stock cats and supplants the factory resonator with an X-pipe.

Let It Eat

The sights, sounds, and numbers from the first 2015 Mustang dyno pull

By Steve Turner

Our friends over at Lethal Performance posted this short video clip of a 2015 Mustang GT running on the dyno courtesy of Gibson Performance Exhaust. Not only can we can hear what the car sounds like at WOT on the chassis dyno, but we get a preview of what kind of power the cars might put down…

We should be hearing these sweet sounds as soon as the real cars hit the streets. For now, let’s enjoy the sounds of this little spy vid. What do you think of the car’s exhaust tone?

This is the Gibson after-cat exhaust system tested in the video. It takes over just after the cats and replaces the stock system with 3.5-inch piping and 4.5-inch tips. It is available in the black finish (PN 619013B) seen here, as well as stainless steel (PN 619013). Gibson is claiming stout gains of 32 hp and 34 lb-ft at the wheels from this upgrade.

  1. hmm, not sure about that exhaust routing for road course use. a catch can is already mandatory for the rear ends on these heavy cars, and i doubt that’s going to change with the ’15.

  2. It would be a more honest assessment if they smoothed the data and gave an average increase. Better yet, take the average of several baseline runs compared to an average of several runs with the modded exhaust. It would minimize measurement error and give a truer number. The way it is presented here they are very overly optimistic advertising those numbers.

    Central Limit Theorem, yo.
