I would go for a catless downpipe + tune. Could be the cheapest and most successfull way
How does the valve control res delete works? They added a pipe around the resonator?

Catless both smells and it's too load. All in scenario for me is BM3 + Catted DP + Resonator delete. But I'm afraid it's going to be too load! I'm not ready for all in yet. I promised myself last month I'm gonna stop purring money into this and put it towards the M5; but hear we are 😂😂
