EXPLANATION OF THE B8 S4-S5 Q5-SQ5 C7 A6-A7 EXHAUST SYSTEM:

There is a lot of confusion surrounding the B8 S4-S5 Q5-SQ5 C7 A6-A7 Exhaust System Setup mostly due to the current “brand-x” systems available on the market. The B8 Exhaust can be split up into 5 parts. Starting from the outlet at the cylinder head you have the exhaust manifolds, the cat or test-pipes, the downpipes (this includes the x-pipe on the JHM B8-S4-S5 Q5-SQ5 C7 A6-A7 Full Exhaust System), and the remaining portion that includes the mufflers that exit at the rear of the car (sometimes this entire section is called the cat-back). See below for a diagram of the JHM B8 S4-S5 Q5-SQ5 C7 A6-A7 Exhaust System:
