I am new with cars and don't really know a lot of the terminology. Maybe if we get a thread that explains what you guys are talking about it will elimininate so many repeat questions. I have done research online but no websites actually explain what these parts are and what they do. Here is a small list of some of the terminology I would LOVE to be clairified:

-Difference between axle back and cat back
-S pipe
-mid pipe
-resonator

 

Axle-Back - From the Rear Axle back changed
Cat-Back - From the Header/SPipe Back (on the tC)
S-Pipe - A Pipe that looks like an S coming from the header to the midpipe (Generally restrictive stock on the tC)
MidPipe - From the S-Pipe to the rear axle that contains the second cat and resonator
-Resonator - Helps quiet the exhaust... and is located an the last part of the midpipe.
