Could someone explain how a G37 exhaust is setup?

What is the difference between a midpipe and a Y pipe? where are the CAT's housed?

what are exhaust headers?

is it engine->exhaust headers> ? >?>mufflers?


what are the components of a catback exhaust?


What consitutes a "full exhaust" vs cat back exhaust.


I see references to X pipes or H pipes where do they fit?


Thank you very much.

 

one word: Google
another word: search

Those two things alone will help you find the answers you need young grasshoppa.

we're all too lazy to try to explain it.

 

Factory Setup:
V-Engine -> Header on each cylinder bank -> catalytic converter after every header -> y-pipe connecting both cats -> mid pipes -> Muffler. Here's what the OEM catback looks like (not as shiny though)



Aftermarket exhausts can get creative though with all sorts of swaps, pics and threads are all over this place
