hey i got the origional 40 series and i have an auto matic tranny.. The thing is my buddy with 07 4.0 auto ranger got the exact same muffler put in. but his piping was all left stock, so its not the muffler thats makeing the sound quieter its deffinatly in the piping, im thinking its the 2,5 inch pipe from the cat to the 40 series, its like 3-4 feet and im guessing that alot if the pressure gets redused in the bigger pipe therefore there woun't be as much sound.
I duno any thoughtss.
