To me it was less work to put plugs in my cooler than to do what the link did. Also they say the up pipe will eventually break because it has 2 flex joints and is no longer supported by the egr cooler. I didn't use freeze plugs in my stock cooler but I did weld plugs in the ends of mine. I don't recall the size other than both ends were different. We made the plugs out of stainless to fit snug and tig welded them in. I did it because I wanted it to look factory and have heard stories of leaks from some of the other setups. I wasn't going to spend the big bucks for the bullet proof delete kit that is the same thing. Since the exhaust is blocked the coolant will be contained if it blows but since there is no exhaust flow though it now I doubt it will ever blow now. I'm not worried about it clogging up either as the passages in the cooler are pretty large. Since yours already blew out you will have to block both ends of the cooler the keep you from loosing coolant. I personally didn't like the freeze plug idea. Good Luck
