To remove your stock exhaust, unbolt it from the clamps located just after the manifolds then remove the whole exhaust system.

Now, let's talk performance! According to Gibson, this free-flowing Mustang exhaust system allows up to a 35 horsepower gain and an additional 45 lb/ft of torque! We figured we would test these numbers on our dyno. While we didn’t quite hit the claimed numbers, we did see some performance gains. You can watch the dyno video below.

Final Thoughts

I personally got to enjoy this amazing sounding and powerful exhaust system on our 2015 Mustang here at LatemodelResto. While adding extra volume and tone, the obnoxious factor was nonexistent. That annoying drone noise that you get from some other exhaust was near minimal on this Gibson exhaust! This made driving the S550 Mustang enjoying since you are still able to hear the aggressive tone from inside the Mustang; while others outside, they get to hear nothing but head turning muscle car sounds.

All in all, if you plan on doing this installation yourself and in your own garage with hand-tools; you are looking at about a 30 minute installation! That is SUPER quick and easy! I absolutely loved the black-tip option that we had on our 2015 5.0; but even more than that, I loved the additional power and aggressive sound!
