Where for art thou, Boomgear?

Wait, so the OEM valve motor gets moved (im assuming to keep for no CEL), and in its place is a aftermarket valve motor and controller thats on the new exhaust valve? And the after market part is more resilient to heat? Im not sure what im looking at.

Me either, but im giving it a try to see what it does. Here’s the instructions from Mach5 that does the same.

Yeah, that weird. In my head I thought they just removed the valve completely and had the controller just working 'in air' so that the car thinks the controller is still doing it job but is in fact controlling nothing. Then the new exhaust is valve less. I guess I was completely wrong! haha

Yeah I just want to know what is the usage and practical difference between this setup vs something like the milltek controller. And if there are any advantage/disadvantage.

There are definitely non-valved mufflerless pipes for the emira i4, and i think milltek controller would work there for the valve motor just mounted somewhere.

Something like this.

Something like this.

Curious what that would sound like (other than being loud).

This technically wouldn't sound any different from our current aftermarket exhaust offerings when the valve is set to open, since the open position routes exactly like this, basically all of them.

You can also do that too if you have no use of the close valve application.

There is a difference, just subtle, but mostly depend on how well the cat-back exhaust was designed.

The stock exhaust is actually pretty good except with two problems. One is that the area before the valve has a leak so when you are on open valve mode not all exhaust flame will exit through the straight pipe but some enter into the muffler can. Second is the tube ends where they meet with the tips are not fully inserted into the tips so some of the sound exits at the bottom of the car rather than from the back of the car. These are some of the details you should look for on an aftermarket exhaust.
