Definitely. A wastegate muffler will be required for me to meet the 90dB goal, I just haven't figured out an elegant way to plumb it yet and not affect boost creep in high output engines. Any occlusion past the waste gate actually increases performance by putting back pressure on bypassed flow which in turn increases the boost level.
