DISCLAIMER: the procceding suggestions and how-to's are for off-road use only and not highway use, obey all local laws and regulations. with the CYA outa the way, the early 308's used eithier a carb or k-jetronic injection. closed loop fuel systems. with the advent of draconian smog mesures the cars were fitted with cats and airpumps. these measures although did somewhat improve the air quality they really choked the motor. so with that, when removing the cats does one need to bother with removing the air pump system or just remove the belt? i'm completly aware of the smog related issues with older cars but the laws are really strange that my 71' gas belching big block ford is legal on the highway but a non-cat ferrari isn't. consider i drive the ferrari far less than the other cars, its very strange. back on topic; looking over the system its quite the maze of hoses and valves. would removing the system entierly cause any issues? thanks..
