the middle bottle ("resonator") in my A4 B6 is toast beyond repair and there does not seem to be an aftermarket can available.
So before I bring $450 US to the local audi dealer I should ask this: is there a catalytic converter on the way out or anything else?
I'd rather understand why the rear exhaust cans are in good conditions while the middle has rotted off the support bracket on a not quite 11 years old car.
Would like some insurance to avoid ordering a $450 canister twice.
The part has a single input from the (cat? engine ports?) and splits it into two exhaust cans sitting in the rear of the car.
tnx
