The twin pipe exhaust system looks excellent and fools everyone.. and ok so the silencer on the left is a look-a-like, but I made this as I wanted the balanced look of twin silencers which you cant buy for the 800, but needed aditional storage space, so this mod killed 2 birds with one stone.! Unbolt the exhaust tip with 2 screws and inside is enough space for a footpump, tyre levers, tube repair kit, and a spare inner tube.
