Ok last time! Please only professionals! Muffler inlet size
yeah i was going to say that too, but i was assuming he wants to know because he will do it himself ! but never really said what he was looking to do go dual or stay single and just replace the muffler.

if you are installing the muffler by a professional at a muffler shop, it doesn't matter what size you get as long as you got a bigger size than what you have. b/c a muffler shop can adjust a pipe to a size. Trust me i used to hang out at a muffler shop when i was younger.

My 03 4.7 QCSB, had 3"in 3"out. 100% positive.Just had a muffler installed last month. But really when in doubt go measure the thing yourself. Much easier than starting 4 different threads... Good luck on the exhaust btw.
