B pipe is the middle part of the exhaust, from the manifold to the back box.

Hopefully this will explain it:

It's the section of piping from the catalytic converter back to the muffler. On our cars it contains the resonator.

Cat-back is just slang for a catalytic-back setup, meaning that you can keep your stock catalytic converter to remain street legal. Usually they consits of a B-pipe, a muffler, and maybe a few smaller pipes for connection reasons.

Not true. That would include the Cat.

 

[dotty]

The cat is part of the 2-1 section of the manifold is it not???

 

[Stoo]

It is Dotty.

You are correct.

So the B-pipe is in fact the part between the manifold and back box.

Obviously this is for a civic not a dc5 so the parts look a bit different but the layout is pretty much the same
