3.9 Exhaust Diameter
Hi guys. I joined this forum about a year ago but have never posted. Just a quick question. I searched but found some conflicting info. I have an 02 3.9l and want to know what the stock exhaust diameter is. The tail pipe is 2.5 inch, but is it the same diameter from the cat back? I kept seeing posts about it being 2.25, but my tailpipe is definitely 2.5. Thanks.
