I have a 2000 blazer 4x4 with a cat converter problem... (the internals are rattling) and it is super annoying...I'd like to get a universal slip fit and I'm not sure what to get be a hi flow or oem and don't want to spend the $ on the full y pipe. Can anyone get me the length of it being it's raining here and I don't have a tape measure....or a part number or some kind of link for a cat that's cheaper or same price as a magnaflow? Flowmaster will work as well or any other options....hi flow being my number 1 choice though thanks!!!! Also I am absolutely positive it isn't the heat shield as mine is already removed...
