I have been considering electronic cut outs for a long time. You get the quietness your passengers and neighbors enjoy, but can open it up when you get away from people and let it roar. And you can fine tune how far you want the cut outs to open just by turning a knob on your dash.

for the vibrant resonator size does it matter if it's 2.25 or 2.5 for the 3.0i, I know the xpipe I have right now is 2.25, just curious?

I believe when I swapped the 4.6 mufflers and put those on the 3.0i those are 2.5 and the guy at the shop mentioned he had no issue welding them on.

The best was the n63 upgrade. Beat exhaust note! My wife literally called in therapy!

(For clarity we upgraded the 3.0i to a 50i X5)

The second best: n55 in the 35i. That one I can use the bimmerlink app to open the second exhaust pipe and it sounds very nice.

Def look into whatever mod it will take. I'm looking into adding a vent on wife's F10 (535 x-drive) becusse she doesn't have the exhaust flap I do it just must have a quieter muffler and both tips active.

305 HP and gets 25.5 avg mpg! Over 50% better than our 3.0i and 35% better than I usually get with same motor in my X5.

Back to topic; for a manual option, installing a plumbing fitting with a simple ball valve was the easy option. I think the guy used a 1/2" or 3/4" ball valve. I can't remember what he uses as the bung, because cast is hard to weld and stainless isn't a cake walk either

thanks buddy, I'll look into that, I was hoping someone would just say you can use the 2.5 vibrant resonators and I should be fine lol found a good deal on fb marketplace

For a preview pull out one of the post cat O₂ sensors.

Yeah not trying to put a damper on the thought of doing a proper replacement resonator just sharing a thought based on a YouTube video I saw recently and my own desire to pump up my wife's F10 muted exhaust.

She went from X5 e70 50i with the most amazing "exhaust note therapy" to almost Lexus quiet F10 exhaust.

You can hear the exhaust note on heavy throttle and it even sounds good. Just sounds much good-er on my X5 with the exhaust flap open.

this is basically what I want to do but with the 3.0i, I already have an xpipe installed and the 4.6 mufflers on my E53

Better yet! You already have a perfect spot for the vent. You can add a solenoid control vent and you can start with a bigger hole and add a reducing insert if it's too big.

My first test with the open flap I just unplugged the vacuum line and put a screw in it. I could manipulate the flap open/closed manually and I figured out that 3 or 4 hours is the limit before it gives me a headache. Fortunately I discovered I can perform the function with bimmerlink so I set it to auto for freeway driving and open the rest of the time.

simplicity is key here I'm not trying to break the bank but I appreciate the suggestion lol
