So I'm one of those guys that likes hearing the hum of the engine. With that said, I recently went out and purchased a Spintech 9000 to replace my factory muffler. Had the muffler installed, two tailpipes installed, the factory resonator removed, and it's still quiet!
This is now my 3rd 4th gen Ram (the two previous being 1/2 ton trucks), and this one is by far the quietest I have ever owned. I expected the 6.4L to have a nice throaty sound. Now don't get me wrong, it's certainly louder than the stock setup, but it's not loud. If anything, it's just a bit deeper sounding.
To my knowledge, these trucks come with one resonator from the factory. It looks to me as though there are two cats prior to the muffler heading into the manifolds. Do these things really absorb that much sound? I mean they're large, but dang. Just a little disappointed here. Anyone else have this experience? I realize many of you prefer a drone-free exhaust. I may look into purchasing some performance cats unless anyone has another suggestion (PA requires that the cats remain intact). Thanks!
