I had Sato Banzai's, but to be quite honest, they were just too loud for me. Plus one side was banged up from a low side on the Poconos, the other side banged up from a low side on the streets.
I must say, the lows dont seem like they are all that much quieter then the Banzai's. I was expecting it to be a lot quieter given everyone says the Banzai's are a lot louder.
I'm keeping my banged up Banzai's as track pipes though. Dont know if i could stomach denting up another grand in pipes.
