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 bonded e-glass and stainless steel mesh. The RPT designation comes from adapting the design of Cobra's Race-Pro 4" muffler into this 3" size. The bodies begin as 3" at the front until they expand to 3-1/2" at the rear. Tip is the Race-Pro machined design that's held in place with 12-point bolts.
