Thank you so much for that! I had no idea you could just unbolt it and put the new one in if it was a MB cat? The exhaust still looks brand new. It doesn't even have the rusty look to the pipes that every car I've ever had in the past has had. I'll look into the price of them. If not I have a guy who "takes care of me" when I utilize him and if I buy the magnaflow, he'd just weld it in for me for prob $50-100. Thanks for the help!!
