Okay, Merc. What have you done to the exhaust? That's almost identical to the sound I'm looking for...subdued at idle/cruise but nice and beefy at WOT.

Yes, it's the 5.3 and I do believe it's throttle by wire, even though I haven't actually verified it yet.

That is 100% Factory-issued stainless steel exhaust right there. You have a newer model, and the stroker engine, so GM might have put a different muffler on. If you are really looking for a nice beefy sound on throttle, but quiet at idle and highway with little resonance, I'd go for a Magnaflow or Corsa. Those two are prohibitively expensive for me though. You might look at Hooker Aerochambers or some of the mufflers Spintech makes. Both are good choices.

hmmmm...I guess GM really managed to "improve" the noise levels of their trucks

I was considering those two brands, but I'm still researching so we'll see!

whoa...mean sounding exhaust from the factory

Darrel, nice truck. Have fun with the extra liters of displacement.

I wonder if the American Racing Torque-Thrust ST's fit that truck. If they do, chrome 20's would look great on there, especially if your keeping the chrome.
