5.9L Magnum Exhaust Q's

I had the edelbrock shorty header on mine (99ram 360) and my buddy 2000 4x4 but basically the same truck had the Mopar performance long tube headers and it seemed he gained way more bottom end than I did with the shorty's, we both had the 3:90 and after the header install he could beat me off the line. As before I could take him off the line probably do to the weight advantage. So if I had to do it again, choose would be obvious for me.

These headers were a funny design, they were 2 tubes into one tube about 6 - 8 inches from the head and then joined to one tube down low, they seem to work well.
