The Grand Prix Slip-On is a great way to amplify the sporty features of the Harley-Davidson Street 500 and 750. Inspired by the MotoGP race circuit, the Grand Prix Slip-On is guaranteed to stand out with its chrome hex end treatment nesting inside a contrasting black ceramic coated billet end cap.
Don’t be fooled by its good looks, the Grand Prix Slip-On is not just for show. Inside the 4” muffler body is a free flowing, stainless core baffle wrapped in dual-density packing. Engineered to bring the Street’s potent power plant to life, the Grand Prix Slip-On delivers increased performance, and a sound so deep you can feel it.
As with all Firebrand products, the Grand Prix Slip-On features Firebrand’s hand crafted, high quality fit and black ceramic finish.
