These slash-cut exhaust tips are slightly different because they are made out of aluminum and the way the edge is machined. And for the bolt-on guy…they bolt-on in minutes in 4 rotational orientations. The tips fit all 2 ½” pipes including all the 2-1/2" Vance & Hines Big Shots, Long Shots and Straight Shots exhaust models. Applications available for some metric cruisers. Kewlmetal.
