Okay, so a while back I had a Flowmaster "Super 40 series" muffler on my jeep. I heard that the "original 40 series" muffler was louder, so I went ahead and bought it and put it in place of my super 40.
Sadly, it is in NO way louder/deeper/better in any way, my girlfriend notices right off the bat when I switched over and so did my father.
I called Flowmaster to tell them my dilema and they assured me that the original 40 should be louder than the super 40. .. Which it isn't but how can that be?
And what about the super 44? That's also supposed to be loud, yes I like loud!! I know many people don't but to each his own.
Any help is appreciated, also I am running stock pipes with no cats all the way thru (don't judge me)
