exhaust suggestions 535i
Car is a 2010 535xi (e60)
So I see my exhaust has valves from factory, I don’t see a ton of info on this. Is there an exhaust system that can use the factory vacuum system for the valves or am I best suited to piecing together my own with a velvetronic muffler etc. and having it welded together? I have vrsf downpipes on as well. Thanks.
