on the 4.0L SOHC, I find the Super44 sounds best in my ears. Loud, strong, powerful sounding, really deep sounding as well. I've been through like 6 muffs figuring out which one i like. Finally found my answer after many many trys. lol.
heads up....ebay is cheap for flowmasters or any muffler for that matter. I think i got my super44 shipped for like $80.
