cat with no air pump
besides it burning out the cat alot faster/clogging. what are the cons of doing this?
the car still has a high flow cat and i installed a enigne without a air pump because i will be replacing it the exh. system very soon
my car was smoking alot around the cat area within the first 5-6 mins, it had a major oil leak before so the whole under body was soaked with oil so i pressure washed it. but i think its just burning off the crap

Absolute Power is Awesome
The air pump adds oxygen to the catalytic converter to complete the oxidation process of the exhaust byproducts because there isn't enough oxygen in the mixture leaving the engine. This is an exothermic process, meaning it releases heat, meaning it actually makes everything HOTTER. The air pump does NOT cool the cat.
Without the air pump, your HC and CO emissions will be higher than they would with it and it will smell worse. The cat may stop working correctly over time, but it's not because it burned up or clogged, it's because the coatings used to catalyze the oxidation process become covered with these incompletely combusted products and can no longer perform their function. If the cat is of good quality, it won't clog or burn up without the air pump.
