Nice throaty sound at idle, reminds me of old muscle cars. At higher speed though, sounded a bit ricey (could have been the mic though). Personally, I don't care much for any backfiring.

I, too, am running the Varex, but through the factory cats and stock manifolds. It's not quite as raspy, but that's okay with me. I'm running it in the mostly-closed position, though.
