I have stock DP’s with the full Meisterschaft system (non valued) and I get drone at 1,800-2,200 RPM. I would have gone with the valved set-up if I was going castles DP’s but I may have to adapt the valves in as at cruising speed it’s more than I want. The set-up sounds awesome running through the gears otherwise.
I had the Soul Performance “resonated muffler delete” prior and that droned as well. Starting to think all may have some at this point. The GTHAUS team are great t work with, does the valved set-up control the drone if that’s what you have? I would hate to adapt for 20% of the time I drive the car in more traffic or steady hwy pace.
