There's so many words for similar things but here is what I know:

from the engine the exhaust gases pass through the exhaust manifold or header, from there it goes through the cat. converter and on to the muffler or exhaust

now, where in here is the B-pipe? where is the axle-back? Thanks.

 

The B-pipe connects to the cat. converter and the the muffler (sometimes called the axle-back) connects to the B-pipe.

Here is a diagram which may help you out.

 

How much would someone expect to pay for a used ITR B-pipe? I always thought it would all come together when you buy the cat. converter or the muffler

 

i paid $100 for mine...it's from a 01 itr...

 

dang, I never knew that...... ok I'll expect to pay around $100 for it....
I'm off to buy some ITR exhuast stuff

Thanks!
