How loud and how's performance

Compared to like khrome werks

As far as loudness goes, it's difficult to say since none of the manufacturers provide sound output numbers. In terms of performance, a 2-into-1 exhaust is always going to perform better, when properly tuned, of course, than a 2-into-2 or 2-into-2 system with a crossover pipe, with everything else remaining the same.
