2004 denali resonator

Yes, the vidoes I have on my youtube are all of the OEM 6.2 muffler and resonator. I originally had the resonator removed but it made the truck vibrate too much at a certain rpm and didn't really change the sound so I had to welded back on. My exhaust actually came from a XL/ESV model. The shop just used a y-pipe to make the factory dual exhaust pipes on the Denali go into the single inlet 6.2 muffler.

I actually bought a MBRP exhaust for a 5.3 Tahoe and then decided it might not be worth the effort to make it work. I was thinking about getting the system on ebay, making one or just swapping out the stock muffler. I was hoping to improve gas mileage but it sounds like that won't happen based on everyone else's results. I can see a weight savings benefit from swaping the muffler but the stock piping looks pretty good.
I'm selling the BNIB MBPR exhaust if anyone wants it.
