So I've been trying to add both of these for the slight performance upgrade and hopefully some mpg help, the catch, I'm broke and figure buying used is cheaper but is it worth it? I have a '12 box and I'm looking at an intake and exhaust that came off of an '08. injen intake with TRD exhaust the guys said he'd do $375 or both. More than likely going to need a gasket for exhaust and he said everything else is there for intake. Is this worth it? Should I just go new? Will everything even fit? Thanks for the help as always guys!
