Hello guys! This is my first post here (I'm from Sweden). I'm interested of buying the Barracuda 4in1 system for my Kawasaki ZX7R -97. Since people in Sweden know nothing about the Barracuda system (nor do I) I registered here to ask you guys if it's any good? Since it's German you guys maybe know something about it? It's really cheap and it looks good, but how's the performance?

Thanks!
