Does the M2 exhaust add any power if open?

I can program it to be closed. My question is does it cause any performance loss leaving it closed apposed to auto or open?? Did lots of searching couldn't find anything. I coded off the ASD and would like to keep the exhaust closed . Not into noise unless it makes more power being open or set on auto... getting old.. Thanks carl

You are saying the 'open' valves ONLY add sound? I don't think that is how it works!
