Audi RS4 Miltek exhaust upgrade
Today we had an Audi RS4 in for fitment of a Miltek cat back exhaust system.
You can see the fantastic performance gains from this naturally aspirated v8 below where we did a power run before and after.
Run 1 (stock): 438bhp & 314lbft
Run 2 (w/Miltek): 456bhp & 330lbft
