Have a 2014 DC, 2.7 and would like to possibly install the TRD cat-back system from the 4.0L. I've looked under both trucks, and the plumbing looks to be the same, right down to the hanger points, but something might be different near the flange, I just couldn't really tell from a quick glance.
Either way, if the area near the flange is slightly different, I could possibly have an exhaust shop weld it where it needs to go.
Just wondering if any 2.7 owners here have done this, and was it worth it? IMO the TRD exhaust sounds perfect on the 4.0 V6, so my guess is it would sound pretty good on the 2.7.
