Stainless Works incorporated 3-inch tubing into their X-pipe crossover -- a tremendous improvement over the OEM exhaust. Additionally, this set features polished quad tips, along with a double-wall conical setup. The primary component of this system is corrosion-resistant, highly durable, TIG-welded 304 stainless steel. The components of this exhaust system have been tried and tested by Stainless Works’ team. Whether it’s increased horsepower, better torque, improved fuel efficiency, or a combination of all three, you’ll definitely be satisfied by this product.
