Stainless Steel

The Super-10 Series mufflers from Flowmaster take the sound and performance of traditional Flowmaster mufflers and turn it up to 11. With a short, single-chamber Delta Flow design, it is as close to running open pipes as you can get. Each Super 10-Series is made from 409S stainless steel. Body measures 9.5" x 6.5" and a height of 4", overall length is just 12.5".
