I'm a Flowmaster fan, so I recommend the FM Super 40 (wake the neighbor up loud), or you can try the FM Super 10, which is a single chamber muffler (wake the entire neighborhood up loud)... Since you're no longer CARB compliant anyways, you could always just go with a straight through Racing Bullet Muffler!!!

get resonated tips... and play with the exit pipe lengths to find the "smooth" tone...
