Hi.Anybody from puerto Rico. I have a 2010 civic si coupe with it's only upgrade being a cold air intake and not sure what to put on next any advice would be appreciated and as u can I don't know much about cars but iam willing to learn
Im not from PR, but i think can help you anyway.
First of all, start searching the "Bolt-Ons" forums an you will find tons of information!
I think your next step is a good Header (2.5 inch collector), exhaust (2.5 or 3 inch exhaust), and Flashpro... and enjoy your new power :vtec:
