Thumbs up

On a car with stock manifolds/cats, it is not real loud(but certainly not quiet either). I have it on my mostly stockish LS1.

I've heard a couple LS1's with LT's(cats & off-road pipes) and they were very loud(especially without cats).

On an LT1, the GMMG is also going to be very loud without cats.

But...This exhaust has absolutely NO drone at any speeds. That is why I love it so much(as well as the awesome muscle car rumble).

You should read this other post and here's what I have to say:

I had the Corsa, but now I have the GMMG. I wanted the deep rumble sound, but the Corsa is like a screaming ferrari sound. They are like opposites.

Here's some GMMG sounds:

Only mods were FLP longtubes.
Those are recordings with FLP's with cats and GMMG (stock cam)
The GMMG doesn't have a drone. Without cats it's definately going to be loud.
