Former Moderator. RIP Icemark.
Helps if you put what model you have...
But for Turbos and on 89+ coupes it feeds air into the cat converter to keeop it from burning out.
On non turbo S4 models it also feeds the cats, but also feeds the aux port solenoids to activate the aux ports.

if you have a series4 non turbo, you will see a decrease in power from 3800rpm up. The split pipe helps the actuators for the auxilary ports open, via backpressure from the exhuast.
