Hey guys, Went for a safety as my dad is passing the runner to me, and turns out it needs a muffler. Its a 99 limited 4x4 and I know mufflers have been discussed multiple times on here, but I couldnt find the answer to this question. I was looking at a flowmaster 40 series, and i understand it is 2.25 in center/2.25 out offset, but what kind of modfication will be required at the shop when i bring it in? Really appreciate in advance the knowledge you guys have to offer.
