Explain this one to me????

Well you can just take yours off, and put them on mine, and we can G tech the car. Then we will know.

The Gtech is inaccurate remember.... And they will be coming off when I put headers on.

The G-tech is accurate, if you set it up right So if the hp goes up between mods, then I will know.

As my experience goes, I revert back to my early days as an acoustic technician. I was working with a couple of guys that were into Lotus's, Mg's, and Go-Carts back in the early 80's.They had a sliding exhaust system on one of their go- carts kindo like a trombone slide. The theory was that they could match the standing waves of acoustic sound to the resonant frequency of the power range that they wanted the engine to run the strongest. IE: The longer the tube, the more low RPM power and the shorter the tube resulted in high RPM power.
So on an 8 cylinder 4 cycle engine, at 2000 RPM with a single exhaust, the resonant frequency would be 8 Khz.
But on a dual system the resonant frequency is cut in half, because each pipe goes to 4 cylinders so it would be 4 Khz.
So long story made short... by putting on dual exhaust you gained more low end power, to gain more high RPM power you will need to put a resonator farther up the exhaust system closer to the engine. That is why open headers or headers with the mufflers directly attached to them give better high RPM performance.

I just can't wait till I bolt on Headers, then all he will be seeing is my brake lights.
