The Royal Enfield 582664/D Exhaust Pipe Assembly is a genuine OEM exhaust component for the Royal Enfield Standard/Bullet and Electra family.
Royal Enfield genuine-parts data identifies 582664/D specifically as “EXHAUST PIPE ASSY – STD/ELECTRA.” The catalogue distinguishes this part from the separate Classic 350 exhaust assembly 582661/D and Classic 500 exhaust assembly 582662/D.
The exhaust pipe carries combustion gases from the cylinder head toward the silencer and is designed to maintain the correct mounting position, alignment and exhaust-system geometry.
