Flowmaster American Thunder Catback Exhaust - Stainless Steel (99-04 GT, Mach 1)

Hi I’m Justin with AmericanMuscle.com and I’m taking a closer look at Flowmaster’s stainless steel American Thunder Catback exhaust, fitting the 99-04 Mustang GT and Mach 1. The two biggest features with this system are of course the full 409 grade stainless steel constructions throughout, and also the super 40 series mufflers, which give you that classic Flowmaster throaty rumble. The stainless steel tubing features a 2.5” diameter and mandrel bends throughout, all of which exists through these 3” hand polished OE style tips. Due to the design of your factory exhaust you will need to cut it off in sections using a saw or something similar. Once you get that out of the way, getting the American thunder bolted up, is a pretty straightforward that should take you roughtly 2 hours using some standard hand tools and the included clamps. Now let’s hear how the stainless American Thunder sounds compared to our factory exhaust.... HIDE
