I have a 4.7L, from the Y back a three inch High flow cat, with and spintech prostreet muffler then Three inch all the way back exiting straight out the back. It after having it for about 4 months now. It's starting to get to loud for me. I'm thinking of getting dual exhaust setup, will that quite it down (keeping my spintech) and loose power? Or do I need to switch mufflers?

To me it sounds like crap when its cold, but when it warms up its good.

Thanks Brian

PS.

Here is come videos of it. Tell me what you think?

all you'd need to change is the muffler, your problem is that shitty sounding spintech muffler.
agreed. you should look at maybe changing to a magnaflow if you want it to be quieter but still have a good rumble. if it's still too loud after that then you will need to add in a straight through resonator or glasspack before the muffler to tone it down.

I have magnaflow and love it. Your charging system sure is low. Maybe thats normal for yours but I would want mine closer to the middle.
