Just guessing...

You got it. The idea of the dump came up after the exhaust was already done and there were a limited amount of places it would fit without hindering ground clearance. Trevor was looking for mainly a sound change with it open which it surely does. Actually when open, it flows more than out the rear of the car, so it's reducing some back pressure as well. I didn't just stick it there, I looked at the flow path through the bends prior and tried to place it where it would get some directed flow from the bend just before it. Most ideal location no, does it work as intended, absolutely!

Those cutouts work wonderfully on turbo cars. I have one on my VR4 and with less back pressure the turbos spool up a little faster. Not to mention the sound change is fun in traffic.

This car is sick, love the detailed photos being posted up!
