This is Milltek's large-bore downpipe for the Audi S5 4.2 V8 B8 Coupé (Manual Only). It replaces the factory downpipe with a larger-bore pipe for improved flow at one of the most restrictive points in the system. Check the specification below to see whether this particular version retains a catalyst or removes it.
If the catalyst has been removed, this is intended for off-road and competition use only, and the car won't be legal for road use fitted with it. Check the specification below for this system's catalyst and approval status.

Is it road legal?
Milltek does not list EC approval for this part. Any exhaust used on the road must still meet noise and emissions rules, so check the requirements where you live.
Do I need a remap?
A suitable remap is strongly recommended, as the engine management needs to account for the change in flow and sensor readings. Speak to your tuner before fitting.
How long does it take to fit?
Milltek quotes approx. 2 to 3 hours.
What is it made from?
T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
