I'll second the ôdon't worry about itö. I have the same thing on mine too, I did a little research on it, because I didnÆt like the looks of it either, I agree it ôLooksö awfully restrictive, and I thought the driveline must have hit it with the previous owner too. Well what I found out is on the later XJÆs that down pipe runs a different path than previous years, and the dent is actually caused from the mandrel used to bend the tubing. They showed the cross section of the dented tube, and it is a little restrictive, but itÆs not really that bad. And then the article went on to say with a naturally aspirated 4.0 there was no need to worry about it. It only becomes a concern if you are installing a turbo or supercharger. So if you have money burning a hole in your pocket and you want to make it look better, replace it. If not, just drive it and donÆt think about it.
