Had my Lupo up on a ramp the other day at work whilst changing the oil. Noticed that my Mesh coupling next to my cat converter was a little stained. We fired up the engine and found it was leaking a little gas.. guess its only going to get worse. (also, MOT Failure???) Has anyone had this and what's the best way to resolve it, Its a complete unit to replace, with the cat converter its about £80, so not as much as most but i'm thinking i might not have to... Maybe just cut it off and weld a new one on? Found this website, couldn't believe the name either! http://www.made-in-china.com/products-search/hot-china-products/flexible_exhaust_pipe.html Theres no type of flexible mesh seal i can put on it? Thanks
