So I actually did something to the suburban yesterday...
Before.
After.
I've had the new Magnaflow in a box on the table for a couple weeks now so I grabbed a couple pieces of 3" pipe from O'Reilly and my father-in-law and I dug into it. I was able to move the muffler back a foot or so and still keep it tucked up into the frame. You can barely see it under there. We relocated one hanger, cut the whole system in half and added another set of flanges behind the muffler. Now I can drop half the exhaust system out at a time if needed. Before, it was all one piece, about 12' long.
The volume level outside the truck didn't change as much as I expected it to but inside the cab is much more comfortable. Upon completion we took it for a little test drive, got up to 80mph on the highway and I'm pleased to report that I can comfortably drive 70mph again. It's got a deep tone, the raspiness of the smaller Borla muffler is gone and there's no drone on the highway. I'm happy!

Nicole wants to do the engine cooking lunch thing but I told her that's a bad idea currently because it would taste like motor oil!
