End pot V40 2.0T (Bj 99), type and diameter

Hello dear people, I have recently torn off the pot at my 2.0t (just behind the flange to the medium pot) and now I’m looking for a cheap replacement. I have over 200tkm on it and want to drive the cart for 2-3 years, so it doesn’t need any qualitative orgies in this regard. on ebay I found something, which looks really damn cheap:http://www.ebay.at/itm/36107989034?… only the same looks to me as the endpot of the small gasoline, although according to the description for the motor with 118kw is. the engine code is also wrong according to the description, because the one of the t4 is I think. as far as I know loud forum the exhaust systems are indeed at the 2.0t and t4, so that would not be a problem. I only have to worry that the wrong one is assigned and the diameter is smaller than the one of the 2.0t. can help me there? I really have been trying to find them forever… should you screw so cheaply at it?
