The RPT slip-ons make use of all of the high-tech features of Cobra's regular 3 inch slip-on mufflers, including 2 inch 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 inch muffler into this 3 inch size
The bodies begin as 3 inches at the front until they expand to 3-1/2 inches at the rear
Tip is the Race-Pro machined design that's held in place with 12-point bolts
