Crafted from aluminized steel and finished in a sleek satin black, the original old skool Arion Pacific Tapered Shotgun Muffler is one of our best selling and most popular muffler upgrades. The Tapered Shotgun Muffler features built in, non removable cross flow type baffles that produce an excellent deep bass sound on custom motorcycles such as Triumph, Royal Enfield, Yamaha & V-Twins. The Tapered Shotgun Muffler is one piece, suits left or right side and fits exhaust pipes with an outer pipe diameter of 33-45mm via a 3-stage adapter. Installation is hassle-free - included are a muffler clamp, mounting brackets and nuts, simply position your mufflers and install.
