Crafted from heavy 16-gauge mandrel-bent aluminized steel, this exhaust is built to last and perform at its best.

You can choose a straight-out-the-back look for that classic dual exhaust vibe, or opt for the side exit behind the rear wheels, which is especially handy for towing. To top it all off, you'll find a pair of 3.00-inch diameter highly polished 304 stainless steel tips, proudly embossed with the Flowmaster® name.
Installation is a breeze with this system, as it comes with all the necessary parts, hardware, and straightforward instructions, allowing you to set it up right at home.
