- The RPT slip-ons make use of all of the high-tech features of Cobra's regular 3" slip-on mufflers, including 2" constant velocity cores for exceptional sound and performance, as well as the bonded e-glass and stainless steel mesh
- The RPT designation comes from adapting the design from Cobra's Race-Pro 4" muffler into this three-inch size
- The bodies begin as 3" at the front until they expand to 3.5" inches at the rear
- The tip uses the Race-Pro machined design that's held in place with 12-point bolts
