Thats cool and all, and I'm not bashing the N1 in no way much respect to Apexi, HKS, and Greddy. But from what I heard the Tanabe sounded best to me on a 7th gen civic. Don't know how it sounds on a later model but make note that 1 brand on 1 model will perform differently on another. I say go Tanabe SRM or Gready Evo II. (Careful with the large canister on the Evo though if you plan on lowering).
