I installed HFCs in the down pipes before settling on real cats. With the stock “downpipes back” it still didn’t sound good.

Just throwing that out there in case you guys don’t visit the B8 S4 forum for 3.0T stuff.

**test pipes*** Sound clips of my exhaust. Some rasp now. But droning is nearly non existent https://youtu.be/79NQTnXlpOA
