Does anyone do one with a bypass valve, instead?

I know that it is quite common of Lambo Gs. Basically below 3K you're going through the cat, etc. Over 3K a valve opens and it bypasses the cat and back box, etc. ISTR Larini or TUBI sell them.

That would seem to be the best option, here. Trouble is I guess it is going to be expensive compared to the overall cost of the car.
