Description

The Flowmaster 40 Series Center/Dual Out Oval Muffler is a chambered street muffler designed to provide an iconic, aggressive exhaust tone. Constructed from 16-gauge 409 stainless steel and finished with high-temperature black paint, this unit offers robust structural integrity and corrosion resistance for diverse street, strip, and off-road applications.

This universal-fit muffler features a 3-inch inlet and dual 2.5-inch outlets. Because it is a universal component, some adaptation to your vehicle's specific exhaust configuration may be required during installation.
