What we found out was that the exhaust is designed quite well...
The fiberglass packed section mutes the exhaust amazingly well and the chamber next to it acts as a resonator. It's quite amazing how much this whole setup mutes the sound of the exhaust noise.
The only way to get the burble and the pop was to pretty much straight pipe the exhaust with about a 2" circular cutout of the pipe where the original bend was.
