If one person says that B&B is too loud, then it's too loud. If another says that B&B has great sound, it has great sound. If one guy says Borla is too small of piping and someone else says it looks better, who is right? Additionally, yes, you will lose some low end if you remove too much backpressure on an NA, but you will also gain high end.
And I only reply with wise cracks to stupid posts. I suppose that doesn't really mean that you are a moron, just that you post like one. ;) Just something to think about.
