I am still hunting for the perfect exhaust. Semi- Quiet and great performance... i tried looking up the HKS's System... and i found nothing for the 06-07 Civic at all.... and i looked at their site too: http://www.HKSusa.com and i still found nothing.... you guys know where i can find info about this Exhaust system?

 

hks probably doesn't have an application for 2006+ civics yet. give it some time. 1-2 yrs from now 8th gen civic owners will have at least 15+ systems to choose from just like EGs, EKs, etc.
