The ideal scenario would be full stealth-mode silence so I can sneak up of unsuspecting rice.
I've considered taking all the carpet out and laying down Dynamat. I know that stuff works for interior resonance.

You should try the flopro mufflers that M7 and I use. I originally had magnaflow but it was way too loud. These Flopros are about the same as stock, if you can believe that.

I thought mine was close to stock at first, but not now. It is probably the closest you can get without spending money on the original equipment ones. The resonator seems to have helped alot.

I beat up on a 2wd hemi tonight, it reminded me of high school. He tried for 3 red lights in a row, I was doing 60 km/h by the time I hit other side of intersection, and by twice that distance was over 100 km/h and he was probably 2 truck lengths behind me. All I could hear was his exhaust reving to the sky. I love this thing. And here I was saying I did not buy it for any racing.

Are those chambered or straight through? I might whine a bit about the noise, but in truth it's quiet enough to converse in the truck at any throttle position. Everything is straight through too, I could pass tennis-***** through that system.
I might consider a chambered muffler in the future. I know the older I get the less noise I will be able to put up with. Even the headers ringing with the cam bugs me... lol
