Isn't it mandotory to have working headlights? With the exception of one being removed to be used as an air duct? It would be awesome to have it out the other headlight though!

Come out the same headlight so it dumps right into your intake pipe, duh

I would just leave it exiting under the car to be legal for the classes your car can be competitive in.

I had this same concern, but when I contacted the track officials they told me no side exits because it interferes with their sensors, no hood exit because violates their noise restrictions, I was running a full 3" turbo back with cutout exit straight down to the ground next to the wastegate dump, now I am debating a full 4" straight down to the ground next to the wastegate dump with no additional exhaust. I am in Germany and their rules are super gay, with a noise restriction of 98db (impossible for a racecar) the inspector will ignore the dump only if it not obvious though.

I don't like the heat wrap and the only one that gets hot is the turbo uppipe. Thanks but I wish I'd be able to compete in true street. Stock radiator works fine for now.

We had the exhaust going out of the hood on our True Street car and just modified it to go under the car and threw a muffler on the end of it.
