I have a 99 civic si. I was wondering which cat back system to get either the HKS Hi-Power or the Apexi N1. What do you guys think sound wise? Im leaning toward the HKS. I like those two because the angled look. I dont want a raspy(weedwacker) sounding one. I have a cat back Tanabe sport medalion right now i just want something different. Sorry if this is the wrong thread.lol.
