The local clubs are using 28mm restricted exhaust headers this year for Leopard/Parilla Junior pre-09 engine.
I have a 25mm restricted header. Can this be bored out to 28mm and if that can be done, would it still be legal for TAG?
What is the best tool to do this with?
A lathe and a boring bar.
I am being told that if I bore it out, it is no longer ‘legal’.
I’ll just move the 28mm one I have around between engines until I find a used one. Pain, since I have it safety wired.
What is Junior 3? There is apparently a 30mm header for Junior 3.
