So, it's not worth me having to buy another set of headers and pay another $400 to replace them again for virtually no gains and maybe even lose torque down low.
Here is the link.

So you are trying to say that a test open headers with different header extensions is more valid then a wheel dyne test with the engine in the car with the full exhaust.
I think someone just doesn’t want to change headers so they are trying to validate there decision.
It’s all good it’s your car do what you want.
But I can’t agree.
