Mileage Improvement mods?
I'm new to honda, my last car was a 62' nova. Anyway i bought a 08 civic, and instead of looking at hp gains, i would like to add mods for better gas mileage. Also if i register it at my parents house i will only have to smog it once until i sale it. anyone have any experiance removing the cat or any other smog crap and not having any o2 sensor problems?
