1. The Sharktails feature 1 3/4-inch head pipes with 2 1/8-inch heat shields that cover the head pipes only. The mufflers are 2 1/8 inches in diameter and have removable baffles (quiet baffles are also available). Also included is stainless steel hardware and the mounting brackets (not shown). If chrome isn't your thing, Freedom Performance offers these pipes in ceramic black for that blacked out look.
