well got a 2002 F-150 with the 4.6 under the hood, i like the smooth power it has but, it just sounds wussy, i mean my 4.9 sounds meaner than it. I was wondering if any of ya'll had put a glasspack on your 4.6's, thats what i did to my 4.9 and love it, so im leanen towards the same for my 4.6, what are ya'lls experiences with 4.6 exhaust? Also how many miles have you put on your 4.6? the one i got has 102,000 on it, but i know for a fact they're almost all highway.
I have a flowmaster super 40 on my 98 4.6 w/turndown. I guy I work with has an 03 dodge 4dr with a hemi with the same setup. Mine has a much deeper sound than his, almost like a big block sound.
I just bought a 4.6, manual transmission, 4X4. It has a dual system with some sort of glass packs on it. I'm not a fan of glass packs because they really don't flow as good as a flowmaster or a good turbo muffler, BUT this thing sounds GRREEAAATT!!!!!
I haven't had a chance to crawl around underneath and really examine the layout, but I did see that the way the mufflers are arranged, it would be difficult to just put flowmasters in their place, but when I look around I might see a better way to arrange the system.
I have a lift and can mig weld, but I don't have a pipe bender, so I might just live with this system for awhile.
IF you want loud, go with true dual straights all the way back. that's what i had on my 97 with 4.6 and it sounded awesome, loved it. had a nice deep throaty sound to it
