No Laurence it’s original.I did just after I bought it 18 years ago have a Stainless Steel Exhaust fitted.MILTEC with a life time warranty. She just gets cleaned after every outing. Currently sat over the pit covered over until I am fit enough to drive again. My XJ-SC at 125,000 miles was just as good will dig out some photos.
Cant get used to having to put photos into a gallery and make a note of their numbers before writing. Have never had to do this before.
