Here is a shot of my custom x pipe. I built it based on an article I found on the net that said that there is power to be found in a larger crossover area.



hows it work? I'm having duals installed right now with an X pipe but not like that I'm sure.

And since we're on exhaust, what is the difference between "HP / Magnum, Rams horn" manifolds for the 383 / 440 and stock ones?

Is it 2.5" vs. 2.25" ??
