The 2045 pipe is very linear, I think it's the best for the RB engines, the 2020 is a bottom end pipe, if using the RB header, the 192 is good for mid to top end, best for big track, the 198 header is mainly for more bottom end, best for short tracks, the Dynamite pipes are okay, the best Dynamite pipe for the RB's is the 086 pipe, overall, IMO, I think the best economy will be from the RB pipes.
