I enjoy the powercore4 for my KTM 990 SMR (street bike) but found them way to loud for my taste and for the MIBS; so I purchased these dB-killers; fit is garbage, baffles aren't touching all around the cone cap and each of them was delivered with a different screw.! But, God now the sound is exactly what I hopped for: much quieter than equiped with their stock sparks arrestors but keeping its enjoying bass groove; it is now just a few dB louder (maybe 3 or 4) than my stock KTM exhausts wich are catalised. Ice on the cake: my bike is smoother at low rpm than with the stock ktm exhauts and almost (if as much) as powerfull on the global rpm range than the powercore4 with spark-arrestors. I'm very happy!
