So I'm looking at buying a full voodoo perfomance muffler and manifold set. But I want to know if anyone has one and how it sounds or how they like it. I'm also looking at putting a jet kit but I want to know the best one. I've seen some with both primary and secondary jets or some with just primary. I'm new to the whole carb world. I have a 1997 CBR 900rr with muffler and I believe headers. And the original jets were drilled up a size to help the bike perform better. But its still has troubles.
