Я купил эту Y-образную трубу ходока, установленную на моем Nissan Xterra 2001 года, в местном магазине выхлопных газов, в котором I have worked. done in before back in May. The flexible part of the Y-tube is now leaking quite a bit and you can hear it. How do I get a part warranty? It shouldn't have failed after just over a month of use.
