I was looking at some borla cat back exhaust systems and it seems as though they do not make one for the 4.2.I emailed them to ask what they recommend doing (about a week ago) and have gotten no response. So is the stock exhaust pipe the same size and the cats the same on all three of these trucks? I was thinking (when funding allows) of buying the system for the 4.6.What do you guys think?WIll it bolt on? Will I lose low end torque on a single in single out set up? Thanks in advance
