Hi Colin.
The system has been replaced from just after where the two downpipes collect together. Graydon who made the exhaust said the collector is very restrictive and reckons I would see a few more bhp if is was replaced also. How are you enjoying the new car? If it is still running a standard map I would recommend a remap as it transforms the car. ;-)
Ta,

Graydon made the exhaust for my S4, good job as well plus hes done a guy from my works too. A remap is certainly on my mind and loving the car although I miss the power of the S4 and the V8 noise.
