The classic Purple Hornie tubular design glasspack Mufflers give sound and performance gains that are more than impressive — they're wild! The 16–gauge, 3.5” diameter steel shell encloses an interior spiral louver baffle design that increases exhaust velocity while decreasing backpressure, projecting the sound waves into a temperature fibermat material. Available in an 18” case length with 2.250” slip–fit or choose from three different styles of 3” three–hole direct–header–mount designs.
