The system is finished with 4" mirror-polished slash-cut tips featuring rolled edges, offering a clean and muscular appearance at the rear of your GT500.
Built from premium 304 stainless steel and TIG welded in Stainless Works' facility in Ohio, this exhaust is built to withstand extreme conditions and offer long-lasting durability. Whether on the street or track, this system transforms your Shelby GT500’s tone, response, and overall character.
