Still trying to get my recently acquired CLK320 roadworthy and out of the "Limp Home" mode and out of California. Mercedes wants $2,800.00 to replace the two pipes with the catalytic converters. I'm considering replacing the cats with after-market cats to save money. I need to know the diameter of the exhaust pipe itself and the dimensions of the 4 cat converters. I'd measure it myself but the cars in Fullerton, California and I'm in Las Vegas. Any help would be deeply appreciated!
