I have the stillen CBE and Z1 high flow cats. I love the sound. There's no annoying drone when cruising and it sounds awesome when you open it up! If you go with test pipes, you'll more than likely be getting drone when just crusing. ( don't know for a fact. some TP guys chime in on that.) it's all about what YOU want, there is no best or right answer.
