The Akrapovic Link Mid Pipes are designed specifically for Honda VTR SP1 or SP2 RC51 motorcycles. Made by the reputable brand Akrapovic, come in sets for both the left and right sides. Constructed with Stainless Steel, these pipes offer a sleek and seamless connection point for the motorcycle's exhaust system. Have been used and one Pipe has some gravel rash, as seen in picture, although cosmetic only as doesn't affect the performance. Unsure if they are for the SP1 or SP2 but they are from.the Slip-On system and not the full system. Very rare to find nowadays.
