Electric cutouts, anyone using them?

In the quest for stealth around town use, with the option of track open exhaust.
I was wondering if anyone had used, or has the electric cutouts?
Basically they allow you to open a valve just pre or post cat bypassing the rest of the exhuast system. They look pretty cool.
Just wondering on comments regarding fit, clearance etc.

Thats the plan, though I strongly suspect Ill need my cats once I get my cam in there. Especially for the natural idle test. Cutouts might have to sit post cat.
Just wondering on clearance, fittment issues etc.

No basically you open out after the collectors. Comes out around the rear of the trans.
You angle them out the side of the car.
