I currently have an upgraded exhaust system on the Tahoe:

2.5" mandrel-bent crossover
3" mandrel-bent downpipe
3.5" pipe the rest of the way back
3.5" Donaldson offset muffler

I've had this system for probably 9 or 10 years now, but I'm ready for a change in sound. The Donaldson muffler is huge, and is obviously a much more free-flowing muffler than the stock unit, and gives a very slight increase in tone, but is still very quiet. I'd like to be able to hear the turbo whistle like I did on my 6.2L that had a 4" system with a straight-thru muffler design. It's been so long, but I THINK it might have been a Kennedy muffler? Not for sure now.

Anyway, I'm looking for recommendations on a straight-thru 3.5" muffler brand... something that gives a deep throaty rumble and allows the turbo sound to come through, but not obnoxious or annoying like a straight pipe with no muffler.

I'll check with Kennedy to see if still offers parts and pieces for the 6.5L systems.

Otherwise, any suggestions?
