I have a hole in my header that needs to be fixed. Its very small and is stainless which I think requires some special welding. Someone told me they wont work on my if it doesnt have a cat. Is this true?
i used to have an s2000 with test pipe and was removing the resonator on my stock exhaust and the only thing the guy said was "this car doesnt have a cat and i shouldnt even be working on it" he did it anyways though
