I just ordered my ARH 1 7/8" Headers and catless y pipe. My question is should I go with 3" or 4" exhaust off the y pipe. I am in the process of building a pretty hairy 427 incher for the truck that is going to be blown with a big unit. I don't want to choke my future set up, even though the engine is stock for now. Any help would be great, thanks....

Go dual 3" if you are putting a blown 427 in.
