Product Details


Description for Cobra 3" RPT Slip On Mufflers Chrome

• The RPT slip-ons make use of all of the high-tech features of Cobra's regular three-inch slip-on mufflers, including two-inch 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 our Race-Pro four-inch muffler into this three-inch size.

• The bodies begin as three-inches at the front until they expand to three and a half inches at the rear.

• The tip is also the Race-Pro machined design that's held in place with 12-point bolts.

• Fits stock headpipes

• Easy install using stock mounting brackets

• Made in the USA

Great sound on my Heritage. Very nice rumble at idle. Comes to life under throttle. Not excessively loud. Easy install.

Love the sound
I put these on my 2008 Heritage classic. I am running a Vance and hines rogue. These things sound good. Not obnoxiously loud but just right. A good rumble at idle and a big roar when you get on the throttle.

I was pleasantly surprised after installing the Cobra mufflers how well they sound. Easy install. Although removing my old mufflers was a pain. Overall I’m very happy with them. I’d give them five stars.
