The header in the mega version is the thing that makes the difference because it has a different innner diameter, larger than normal pipes.
This is why it rev's better.
btw the rb 2604, is the same as the 2602 max, maybe you could get your hands on that one.
@ arawark, yes i know, really hard to come by, maybe try if you can order the pipe at a european site, but even i cant get any mega 2602 pipes any more and i live 10 minutes from the serpent factory.
