Im thinking about getting a catback or exhaust with custom piping. I was thinking about the Greddy Evo catback , but I saw one on a prelude and the canister looked huge. You can see the bottom part of the canister like hanging down when you look at the tip. Thats why I was thinking about getting a HKS carbon titanium universal exhaust or an Apexi N1 universal exhaust, because I like the straight threw design.
The problem is I want a catback not just the exhaust.

So what should I do? Go with the greddy or get some kind of custom piping for the HKS or Apexi. Also if I do go with the HKS or Apexi will it sound as good and give more performance like the greddy?
