Cat-back exhaust help
I have a 2007 f150 with a 4.2L V6 and I want a new exhaust. I'm looking at a flow master American thunder cat-back system which fits straight onto the catalytic converter. I have looked at many different websites to try and figure out whether it will fit, but none of them have the V6 option to choose from. So I would like to know whether it matters about the engine size, or just the pipe on the catalytic converter.
