Man. I have a set of valvetronic mufflers that open with vacuum source, usually by their module. My car is supercharged, but would the gthaus module allow me to have the car close at vacuum and open under boost? or open or close with rpm? Seems I've found an interesting situation with my exhaust.
That's a very interesting problem to have. Worse case, you can always just buy a standalone module that build vacuum pressure so the two are isolated and not depending on the motor to build the vacuum pressure
I am grabbing vacuum right at the brake booster. So that should always have vacuum or the brakes will run into issues

I noticed that’s where you tapped it. Let’s say your motor was boosted, wouldn’t that line also see boost pressure? I mean your brakes theoretically don’t need boosted at WOT.
the mufflers are currently controlled by the module it came with, controlled by a key fob. Just not a fan of how aftermarket it is. I want it to feel oem. The key fob is gimmicky to me. I found some boost open valve actuators but they actuate in the wrong direction…
just a tough problem.
Edit, my apologies, didn't meant to hijack your thread.

The RCF Brake Calipers installed along with FIGS/Racing Brakes 2-piece Rotors and Stoptech Stainless Steel Braided Brake lines
Here's some pics of the caliper grinded to make clearance for it to mount with the adapter bracket from 350phi
Heatshield required slight cutting to clear, around the circumference to take a bit of the lip off as well as some for caliper clearance. The rear electronic parking brake is currently left unplugged and disabled with error code on instrument cluster. No solution exist currently as of this posting.
Slight trimming in the front as well, just to clear the caliper. the rest of the shield can be bent out of the way.
Front and rear calipers clear the stock Launch Edition/BBS optional/DHP IS350 wheels perfectly. (unknown if it will clear the stock Enkei wheels, have not seen anyone at this time attempt it yet)
The unused parking Brake connector is heat shrunk for time being to keep moisture and dirt out of it for now
How many conductors is that parking brake wire? I wonder if it's like the airbag system, where it's expecting a certain resistance across two of the conductors in that harness to see if "it's there" or not. Might be worth looking in to.

Its two wire actuator. yes if its unplugged it expects to see a resistance so when its unplugged it will throw a fault. throwing a resistor in place works to trick it to not fault (I've tried it) but my concern is if the switch is hit to "engage/disengage" the parking brake, it will expect a current draw change and the resistor in place will overheat since it is the "load" when 12v and ground applies to a motor that is not there.

I wonder what happens if you unplug the switch that controls is, while there is a resistor in place. Im sure it'll throw a body code, but I don't know that it'll throw an error message on the instrument cluster. Id give it a whirl, keeps you from turning that resistor a bright orange if someone hits that switch haha.
As I was typing that, I realized something else, the EPB cars will apply the parking brake if the drivers door is opened in reverse, so having the switch unplugged wouldn't matter in this case.
I don't know how far you're willing to go with this, but you could always just extend the harness for the EPB in the rear, and store the calipers in the trunk. LOL. Or come up with some substitute motor, or maybe the EPB actuator on the caliper can be removed and stored in the trunk with lengthened harnesses.

yeah thought of this already lol. not very elegant but would do the job. i already found a junction connector for both inside the car for the Parking brakes. Still waiting to see what the new 2023 RCF has before deciding a route to take.

definitely waiting on this as well. Someone said the new 23 rcf had electronic parking brake
