By including everything you want in a slip-on muffler, and nothing you don't, the 4" Loose Cannons deliver style, sound, performance, and quality, normally found only on much higher priced alternatives. On the outside, the highest quality finish highlights the 4" muffler bodies with their distinguishing flash-suppressor end treatments. Inside, the free flowing baffles, featuring stainless cores and dual layer packing, deliver an aggressively deep sound and increased performance. Engineered to get the most out of both stock and high performance motors alike, the Loose Cannons are the perfect choice no matter how modified your bike is. Unbelievable sound and an un-deniable style.
