all the pipes named 053, 063 and 086 are all the same, just made by diff companies, and wayy different pricing. an rb one costs around $120 while an ofna costs around $55-60. big diff, get the ofna since they're basically the same pipe
Yes and no,,, pipes are the same basic shape, but not to the exact "T" ....
if you have to ask the question which is better, I doubt you'd notice much of a difference between brands. Just select a shape that suits your needs/powerband/fuel consumption and/or track. 50-3/53/63/86 = basic pipe shapes..... as a general rule,, lower =lower powerband tuning, higher = a higher powerband "hit" as a general, When you get into different motors they will have their different responses to the pipes, but the above is a basic note for starting out.
If you have been racing for sometime you'll notice a difference it materials and tuning with different brands of pipes(within the same shape, ex. 50/63/86), hence the ofna or Rb Q most raised by peeps that ask..
Rb pipes you'll notice are thinner(metal) , ofna's are a thicker pot type metal. as far as bashing, go ofna its cheaper to replace, for all out racing, the Rb's..
You'll notice that the thinner metal takes heat faster then retains its heat level and internal temps remain the same,, hence an easier and smoother tune, that retains it's tune, because of consistant heat n sound dynamics returning to the motor.. (heat -n- thermals affect resonance timing back to the motor, just like when you first start your motor and you have to get it to operating temps to properly tune it) .. with the Rb its gets there and stays there more consistantly, with the ofna it takes a bit to heat up, then fluctuates with air circulation more than the other because of the metals.. Then the tune comes and goes, not super apparent, but apparent enough for the "more than enthusiastic" racer or circuit/pro .
There's other factors that go into it but thats the basics,, think of heat,, and how it transfers,, look into the materials in all your components,, it will help you be a thorough and knowledgable tuner all around.
