[89IROC&RS]

eh, i dont reccoment people loose cats all together, i mean, they really dont reduce power all that much, and i suppose somewhere deep down , i am a tree hugger, i dont see the need to run no cats, and needlessly pollute. also if you have to pass emissions, you wont, cuz all those do is make your car THINK it has cats, but the emissions that would be scrubbed stil go out the pipe and youll fail emissions. im running a high flow cat on both my camaros, and dont have any plans on going strait pipe. my flowmaster and high flow cat on the IROC are louder, and run better than the strait pipe it had when i bought her.
