Hey I’m Justin with AmericanMuscle.com, and I’m checking out Flowmaster’s American Thunder Cat-Back exhaust, fitting the 98 Mustang GT, and Cobra. As you may know, Flowmaster offers a number of different mufflers, all with their own unique sound, in this case, the American Thunder for the 98 GT is built around my personal favorite Flowmaster offering, the super 44 two chambered muffler. There’s one muffler that really nails that iconic Flowmaster sound, this is it. This system is unique for a couple of different reasons: obviously for the use of those super 44 mufflers we just talked about, but also when it comes to the construction. The American Thunder uses 2.5” mandrel bent aluminized steel tubing, which may not be as good as stainless when it comes to resisting corrosion, but it’s definitely going to help keep the cost down versus that more expensive stainless steel. The tips are OE style 2.5” polished stainless steel, but as you can see that polished finish extends really far back, which is going to make for a nice clean finished look underneath the rear bumper. Because the exhaust hangers were designed differently on the 98, this exhaust will only fit the 98 GT and Cobra, unless of course you modify the hangers. Before getting started with the install, you will need to cut off your factory exhaust using a sawzall or something similar. Once you get that out of the way, getting the new Flowmaster bolted up should only take you about 2 hours from start to finish. Now let’s hear how the Flowmaster American Thunder catback sounds compared to our factory exhaust.
