Bakersfield and Dixon run what is called the Senior Super Sportsman class. This class utilizes an RLV3 pipe. This is a different pipe than the L2 pipe (or any other A/L/G series pipe). It is a smaller pipe than the L2, making it potentially easier on clutches and engines. Both or either club may allow the use of an HPV3 pipe, which can be found used for less money than a new RLV3 pipe. The HPV3 and RLV3 pipe are very similar.
