I have an 04 Mazda 6 v6 and I found headers for a Jaguar 01-02 and since those cars run the same engines as us, do they fit our cars. I've been wanting headers since I got my car and in addition to being hard to find, they're expensive. I just want to make more power
Which Jag are you looking at? Both the S-Type and the X-Type used the Duratec. The X-Type engine is transverse and FWD like the 6 - the headers might fit. The S-Type is Longitudinal and RWD. S-Type headers would not fit.
