i was just wondering what all parts i can replace on my 2000 civic si with other honda and acura parts, i have an exhaust from holley airmass thundermuff, its for an integra but will it fit, or can i replace springs from the integras to my car, just wondering for maybe a list of what people have used that are better parts than what i have stock,

not looking to be flamed but maybe we could make a sticky out of this
