Exhaust flap switch
#16
Hey works_team, I’ve never used systems like these before but I'll be ordering my system from Schmid Motorsport as I've already installed their exhaust. I'm waiting on feedback this week from them as I would like to purchase the system that uses the cigarette lighter but then the lid doesn't close properly. Stefan Schmid says that he has a GT3rs customer that modified the tray so that he could close the lid. Once I have more info I’ll place my order, it will be one of the 2 in the pic. More info will follow once installed. Cheers.

So true, I think unplugged / always open valves will be enough for me at least for a while. Watching the CarsWithLuke vids, it sounds good enough. If I add OPF delete pipes, it will likely be the perfect sound for me.

I am hoping to also fall into this catagory. Let’s see how it goes.

It would be nice to find out if someone cuts open the OPF recepticle in non-OPF regions that it is empty, but we doubt it.

You need delete pipes because regardless of region the metal receptacles / structure is left in there for all cars. The only difference is the OPF filter active coating and monitoring mechanisms of the OPF in regulated countries. The metal recepticle of the OPF (and we believe non-active filter inside) still attenuates the sound in non-OPF regions.

As far as possible back-pressure issues, it would seem that if an exhaust replacement (rear muffler & valves) doesn't cause a CEL or require a tune, then removing the GPF wouldn't either.

Removing the GPF will be fine. The ECU wont know otherwise because ther is no sensor for it.
I was told that here in Australia we do not get the GPF. Well I think we have it, and I bet everyone does.
After 400 kms mashing the pedal. I got zero soot in the exhaust tips, and I mean zero. Its still all shiny in there!!!

”United States models use a straight-through filter design without the expensive, soot-trapping precious-metal coating. This makes them inert and nothing more than sound attenuators.”
If your SA is so adamant have him put his money where his mouth is and bet you for some discount off the purchase of your new automobile.

I just did the valves mod (unplugged both hoses).
I really like it under 4000 rpms. Valves are always open, it’s 15%-20% louder than before.
You hear the downshifts a little more now. Is it a radical change: NO. Is it better: YES. Low end torque; I didn’t notice any change.
I suspect a very subtle resonance at highway speeds (80mph in 6th gear).
Bottom line: worth it. I’d recommend doing it on a lift (takes 20 min). See below how I attached the hoses
