Looking for a little Rumble in my 06 GMC
I wanna get a muffler that gives my truck a little more rumble to it. Im havin a hell of a time trying to find one with the dual inlet and single outlet like the stock one is now. Just tryingto avoid getting the "Y" pipe. Any suggestions?!?

I don't think your going to find a whole lot unless you to a dual in dual out set up or y pipe it before the muffler. You could also go with a cat back system and replace it all.
I just got a Gibson ss dual cat back for mine, and I love it. Its still pretty quiet inside the cab but has a deep mellow tone, I can't stand the cab resonance you get with flowmasters.
Also I think I've seen some suburbans and tahoes that y pipe the dual exit muffler before exiting behind the wheel....you might be able to swap them out03 Silverado 1500

It's a lot easier than it appears. Many aftermarket oval muffs can be run in either direction, so a dual/single setup works for you. A good example is the Magnaflow 12158, which is dual/single, fits where your muff is located, and is reversible. Available many places, including ebay for about $110. Flowmaster makes the same thing, too.JimLas Vegas, NV...2001 Silverado 1500 LT Z71 Stepside X-cab, 171,000 miles, 5.3, cat-back duals, leveling kit, 3.73, 17" rims, more to come...

Aren't magna flows perforated tube? Running them backward would ruin the desired effect of the muffler. Also even on a chambered muffler, the baffles are designed to function in one direction of airflow...and reversing that would change the sound and add restriction to the exhaust system

they post on their site that they can be reversed....so, you guys decide. If you cut open some of the perf muffs, you will see that the perfs are often multi-directional. I, too, had the same concern. But once I saw "reversible" on the description of many of their chambered muffs on their site, I stopped being concerned.
