Re: My new exhaust system
Kempo, the pics of the manifold look like the stock unit. Am I mistaken or did you just increase the diameter if the pipe and muffler? Also, would the hp increase come from this alone or did you place a larger aftercooler? I'm not following this very well.

The manifold is the stock unit but it was cut about 2" higher above the stock 3 bolt flange. This made the manifold exit 3" in diameter to accept the new 3" flange for the new exhaust. That is why the O2 sensor is not on the manifold anymore since the cut was made above the O2 stock bung. The increase in HP was with the new exhaust only. The previous dyno run was with the "300 upgrade" and the larger after cooler radiator.
