hi i want to de-cat my tdi 130 but is it possible to just get a de-cat pipe and leave my back box on as i like it hidden away! or can i just have the cat taken out of my pipe and bodge the whole with another pipe?i know its a pikey way of doing it!
just want to know what difference would be like.
also will a tdi with out a cat fail mot? ive been told diesels dont need cats for mot’s? but you cant believe everything you read!
