When i get headers for my truck is there a diff in the 2 wheel drive compared to the 4 wheel drive. I can't really see any by looking at them. I don't care about the exhauset because i am getting the 4 barellel intake and header plus duraspark to get rid of all the emissions crap and all the other sensors.

 

2wd and 4wd frames are the same so either header should fit.

 

I heard the 2wd headers are shorter than 4wd headers, not sure really!
