Hi, i'm about to buy a new exhaust muffler for my car, but i've seen some options and i can't decide what to buy, i was looking at the HKS Hi-power or Apexi N1, and some others, also i've seen ebay mufflers that go around 30usd, are they good, has anyone here used one of those???, what difference will a muffler like HKS one will make on the performance and sound of the car.
btw, i'm planning on doing a 3" cat back exhaust.
