Another PZEV question...
 

Alright so from what i can tell about the PZEV model lancers the only difference is the extra cat converter... Something with headers as well... I dont live in a state with emission laws so thats not an issue. Is it possible to cut one of the cats off and weld in a straight pipe?... Also... Does just one cat have the o2 sensor?... So i could chop the one without so i wont get the engine light issue?
