Question truck is to loud after Lt's back exhaust...... HELP

i have a 6.oL in my CC and i have pacesetter LT's with a ORY and 5x8 oval 18" body 2.5in and dual 2.5out Magnaflow on it now.... i had the LT's and ORY with stock muffler and it was fine but i wanted a little more sound... but just adding the Magnaflow it is to loud and has to much DROWN while cruising on the interstate....

my question is what is a QUIETER muffler 3" in/out than my Magnaflow but still sounds good... IMO Magnaflow is the best sounding exhaust... and would a 5x11 oval 22" body 3" in/out be quieter than my 5x8x18 2.5 in 2.5 dual out ENOUGH to buy it and have it installed?

if i could get RIGHT IN BETWEEN OEM AND WHAT I HAVE NOW WOULD BE PERFECT

I have a DI/DO 3" Magnaflow, and couldn't be happier. It is a 12599, and my old exhaust was a Corsa.

I have barely and drone at all. I run mine straight out the back with 4" tips. I would make an exhaust clip for you, but my cell phone does it no justice, and that is all i have for a video.

MANGLED03GMC told me about the edelbrock diesel muffler.its got 4" in and 4" out you can get adapters to drop it to the size you need.i did it with a bone stock 5.3 and made the whole unit short enough to fit right into where to factory muffler was and used the factory tail pipe and hangars as well.gotta cut the hangers off the old stuff and re-weld it to a different position.it sounds great.only drones at 2,000 rpm go a hundred above or below and its gone completely. and it is definately free flowing.

A tailpipe(s) will make all the difference in the world...my current exhaust was whisper quiet when it was duals out under the rear bumper. Removed the tailpipes and dumped it under the bed and it was like I put a completely different exhaust on it, hella louder. Gutted the cats and it's almost obnoxious now.

BTW, for future reference...

Drown = when your lungs fill with water and you can no longer breathe and proceed to death...

Drone = Exhaust resonance into the cabin of the vehicle at a certain given RPM
