I was just wondering which one would you guys perfer (via self experience hopefully). Right now I am leaning towards HKS but the only problem is that the description for it says for non Vtec only. If someone has HKS and a Vtec engine and was able to combine the two, would you mind sharing any info on custom fabrication if necessary. But back to the topic of HKS sport exhaust or Apexi WS2 exhaust, discuss please.
