Now it's more kickass sounding. Surprised your dump isn't. Weird.

Popping could mean you're running to lean btw... I used to get a solid amount until I tweaked my mixture. Now I get nearly none, and I don't even run the flying saucer thingy decal valve.

Hope that helps. As Mark said, yank it (er, the muffler) and give it a whirl. Methinks upon which then you'll want to "yank it" 8-)...

Could it be that the sound depends on the type of waste gate, or the restrictions in the tubing from the plenum. I have a Tial 46mm Wastegate and very open and straight tubing in my RarlyL8 headers. Not much restrictions there (although I tend to overboost quite a bit).
