Exhaust, headers, and air intake (which is worthless BTW ) won't hurt your milage. It may even help. A street cam like a ZZ9, LPE 211, CC501, won't hurt that much. Big cam, Heads, Higher Compression can hurt. A good custom chip will be needed with the Cam.

That's the correct answer for sure!Lots of performance parts advertise fuel mileage improvement. That's how you convince your wife you need these parts.
The truth is though, with more power and better sound you'll be wanting to take advantage of it more often, which will more than offset any mileage improvement you might or might not have had.
