I need an axel back or cat back exhaust system, whichever comes my way first, for a 98 civic dx. I'm thinking of going with HKS or Greddy, I want something that you can hear but beyond that, not much. Real quiet. Any ideas on the best place to find something like that? All I see online is $500 for axel HKS and Greddy, they have to be less expensive than that somewhere on the web....
