first mod for me was my Greddy Evo Catback. a good friend from a local forum had an accord but sold it and he sold me the exhaust for $150 and installed it for me man i loved it the first day i recieved it, and still love it today!
I gotta say the first mod I did was Injen convertible CAI/SRI. To this day it is my opinion that it is the best intake out there for the 6thgen because of it's versatility. Next came shifter-cutting and adapter installing..
