eldavo69 Posted August 30, 2011 Report Share Posted August 30, 2011 My mate George has got the full valved Milltek non-res on his RS4 with "motorsport use only" cats. It sounds phenomenal, but yet on the M-way with valves shut there's no droning or intrusive noise. Best part of £3k mind! Link to comment Share on other sites More sharing options...
