My cat converter on my impala is clogged up and I'm thinking about just having it cut out without putting another one in but I don't know if it will affect my car's performance.
My bad famo I really did read your Question.... Some dudes do run a str8 through convertor, which is like not having one on at all. Its sounds kind of odd but, performance wise it made his car a lil faster. here is something I've found Purpose: Using its internal catalyst, a catalytic converter's job is to greatly reduce the level of harmful emissions in a car's exhaust. Namely, these are carbon monoxide, hydrocarbons and oxides of nitrogen. All of these emissions are serious health and environmental hazards, plus they contribute to the formation of photochemical smog. A catalytic converter changes these poisonous gases to harmless carbon dioxide, nitrogen, oxygen, and water. In a simplistic way, the catalytic converter can almost be thought of as an engine of its own. The converter uses fuel and oxygen to "light off" its internal catalyst, which consumes a large portion of the gases flowing through the converter. Although a converter greatly reduces emissions, it does not eliminate them altogether.
