Flowmaster's 409S Fox-Body American Thunder Exhaust

When it comes to adding a performance sound to a Fox body, it can be easy to get lost in the TONS of different kits out there. One name that has always come to mind is Flowmaster, and the famous sound and the 5-liter seem to go together like ice cream and chocolate. Now, Flowmaster has upped the ante, adding 409S Stainless Kits to their already impressive resume of products for the most popular muscle car in the world.
