Ok, I know that I have read all of this information somewhere on here before but for the life of me I can't find it again. So, I have a 2001 4X4 5.4L to run a true dual exhaust setup what mufflers would I need (not brand) for a SISO setup? Would I need an offset muffler, center in center out, and what size in and out? I just don't want to run into any problems once I get to the shop. Thanks guys.

By the way Great Forum!
