I know that stepped headers make some improvement also due to antireverb/back pressure......I've played with the stepped exhaust on my bikes and noticed considerable gains in torque....havnt seen much info on stepped truck headers though....if gains can be made by stepping up to the bigger tubes I would go for it but its gonna take a little shopping to find the tubes and the fit in one package....
Heres a link!!!

I am trying to find answers on fitment but I can't find anyone that bought a set. They range from 1.75" to 2" primary tubes including stepped versions. Might be something to look at.
Just tried to reach them....out of the office I guess....called Stainless Steel Works and they dont build specifically for GMT 400.....they reccomended Southern.....keepin this truck so I want the most durable I can get without grindin, dentin or cuttin stuff up..........
