UUC Motorwerks has finished development and is starting production of their hand made custom exhaust for the AUDI S4. The system is a dual 2.25” stainless steel design, with one silencer, running into dual 2.25” angle cut or dual 3” DTM tips. There is a possibility that different tips will be able to be special ordered. The silencer is custom designed for this application. It is a single canister that is separated into two chambers the length of the mufflers keeping the exhaust flows between the two perforated pipes separate. In the silencer there is a H style tube that connects the two perforated tubes. The area of a standard 3” exhaust diameter is 7.065 with the two 2 ¼ inch pipes is 7.948 . Along with the bigger flow area there is no loss of exhaust gas velocity from the merging of the two small pipes in to one larger pipe. The price has yet to be announced but it will be in the $1000 to $900 range. There have been timed runs on a STOCK S4 (no other modifications other than the exhaust) here is the information:

Stock 30 - 50 6th 8.2 sec
UUC 30 - 50 6th 6.19 sec

Stock 50 - 70 6th 6.9 sec
UUC 50 - 70 6th 6.0 sec

Stock 1500 - 5000 3rd 8.42 sec
UUC 1500 - 5000 3rd 7.61 sec

Stock 2000 - 4000 3rd 17.8 sec
UUC 2000 - 4000 3rd 15.81sec

Doh, I botched the area of the 3" pipe when we were talking. Did circumference instead.
