Awesome numbers. Can you upload a higher res photo of the dyno sheet? I couldn't zoom in enough to tell heads from tails.

The burns stainless is very tempting, competitive price, lightweight, premium quality. How is the exhaust drone between 1k and 2k rpm? Bearable? Droning it's nuts off, or just a dash of drone from 1600-1700?

I'm dying to know. It's the final question mark I have before pulling the trigger on the purchase. That's how much I hate drone, enough to take a 25lb penalty.

Congrats on the build. If you dyno'ed up in Reno, that must have been a decent correction factor on the dynojet from the altitude I bet.

Depends on who you ask. I've heard it is ok, to it is horrible. Drone is so subjective. I know one person went from 4.5" to 6" to 6" dual stage.

From what I get, yes it drones. How bad, that is hard to say an things like cam/headers/etc will effect it. I keep debating one, but like you can't stand drone.

Also annoying how price difference in 4.5" to 6" muffler is like $142, yet they charge $333 more between the 2 systems. WTF is up with that?

Yes it does drone bad below 2200 rpm in any gear on a cammed LS7 with headers and no cats.
I have the large two stage mufflers. The set up I have exceeds the 98 db limit at our local track.
Adding two 3 inch resonators in the x-pipe to try to lower the sound and drone. We will see if that does the trick.

It does drone more than my corsa did but its quieter outside of the car for sure. We're still working out the tune on the car only had 2 5 min street sessions before I had to split so it needs some work.
