Catalytic Converter
My Catalytic Converter has broken down still works but is rattling real bad.
Thinking of replacing this with a Magnaflow dose anyone have any recommendations for type of cat currently running a cold air intake 1999 lt 4 door 4wd 4.3l vortex.
Is there any performance differences my exhaust system has Magnaflow muffler.
