Cobra Motorcycle Slip-On Mufflers
A slip-on replaces the stock mufflers and usually fits onto the existing head pipes. Cobra slip-ons here mostly have 3, 4 or 4-1/2 inch bodies, in chrome, black or Raven Black, for Harley-Davidson Touring, Softail, Trike, Sportster and Dyna models above all, with others for Indian Chief, Chieftain and Challenger, the Honda GL 1800 and VTX, Yamaha XVS models and the Kawasaki VN 1700.

European Harley-Davidson models
Several Softail and Dyna slip-ons here carry a supplier's notice that they will not fit the thinner head pipes of 2017 HDI/EU models, and some fit European Dyna, Fat Boy or Softail Blackline models only with an extra OEM bracket or after drilling the stock muffler bracket. Read the notice on the listing before you order.

Will it fit my motorcycle?
Each listing title names the make and models it fits, with the Cobra part number. The Fitment section on the listing gives the exact models and years; check yours before ordering.
Do I need new head pipes?
Usually not: a slip-on fits onto the existing head pipes. But several Softail and Dyna slip-ons here carry a supplier's notice that they will not fit the thinner head pipes of 2017 HDI/EU models, so read the notice on the listing. If you want to change the head pipes as well, see Cobra Exhaust Headers & Head Pipes or a Cobra full exhaust system.
