The screen at the top is for our Magden System. Its a data logging system its basically like HKS Camp 2 but faster and with more features. You can set it to do stuff like check RPM, oil temp, things like that.
Hey, there's a few good ones to choose from now. You absolutely can't go wrong with the Stillen. It sounds great and has shown dyno proven results from third party testers. That's what I have. If I were in the market for an exhaust now I'd most likely get the stillen again.
