your the first ive herd.. that wanted to do somthing like this lol.. putting a muffler on after a muffler is just going to damper the sound even more.
single chamber = race mufflers loud and less restrictive, more raspy
duel chamber + = street use, less loud but a tad more of a deep rumble sound.
I have Mopar Pphs with a SpinTech single chamber muffler after a high flow cat. Its very raspy at any rpm and with the side exit turndowns i get faces everywhere, although i do have the 5.9 and not the 3.9.
listen to jonnymagnum on this one.
sadly, your tranny is not much different then the 5.9/46rfe combo vs 4.7/45rfe, you have no bands and 2nd gear ratio is set for towing lo and high. So technically it can be called a "5 speed auto" but its not..
The 46re and the 45re both are around 80-83% efficient, which means both loss around 17-20% through the drivetrain.
the 4.7s made less hp and less tq in 2005 at 230hp/290tq
the 5.9 made 250hp/345tq
take your 20% loss from both
4.7 184rwhp/232rwtq
5.9 200rwhp/276rwtq
Yes the 4.7 is a better motor, better technology. The new 4.7 is going to be pushing i think 310hp crank. Not bad for a small *** v8...
o and if you swap out the autos with the 5 speed manual they offered with the sport versions on both trucks (but with the 5.2 instead of 5.9) you get about a 15% loss lot better then the auto, so if you took a 4.7/Manual with a 5.9/Auto would be even then, but the 5.9 with an manual...
o and on a side note, most of Chrysler's Auto Trannys are crap, your lucky to get a lemon in these standards as its rarer to find one that actually works correctly then it is to get one that ****s on itself after 10k miles lol..

user, i have the 5 speed manual. from what i have heard, i am looking at between 15-17% loss, making my power numbers at the wheel go up.
EDIT:
yeah this is what i meant (didn't see it the first time)
