i would suggest keep it stock my friend,these cars not meant for these things.if u modify it then you will see the after effects of modification later on your car.this model is very nice enjoy its drive as it is.if you want decent mods just install decent rims or put iradium plugs thtsit .its my personal experience, i modified my civic 2005 Vti nd spent around 60-80K nd did lot of drags on it nd stuff so i would suggest keep it simple
