Not related. I don't even have that flapper in my exhaust anymore.

The horsepower comes with the stickers.. Golf tee mod alone won't be effective

Golf Tee Mod?

It's makes a marginal sound difference, that is all one should expect from it.

If you are wearing a gold tee while driving you will instantly lose 5/bhp per inch of gold tee, data-log before and after changing from gold tee to white tee and see if your timing flat lines only with the gold tee or if you are also having trouble with the white tee. Report back with .csv files and we will help you tune it out even while wearing the gold tee if possible. Good luck!

Did you disconnect the vacuum line or the electrical connector in the trunk? If you've disconnected the vacuum line, you've vented it to atmosphere, which means no vacuum in the system for your brake booster or to pull the turbo wastegates closed, hence no power. Reconnect the vacuum line and disconnect the electrical connector instead, or at least plug the vacuum line (e.g. with a golf tee...).

Its not the color "gold" but yes the tee must be made of gold as the chemical properties of that metal interact with the steel in the exhaust under hight EGTs to cause a gas mixture which combusts within the exhaust piping, this in turn pulls exhaust gases out of the exhaust piping, fooling the motor into thinking it needs more air to be brought in through the intake manifold. This creates more horsepowa

Be careful
