Default SIII fuel tank - do I need to drop exhaust/muffler?

The manual doesn’t mention it, but I’m not sure how else to remove the rear bolt with the spacers. Heat shield as well? Seems like a pretty big oversight in the manual if so…

Default Exhaust muffler drop

Pretty sure I had to drop or at least loosen the exhaust when I changed my fuel tanks.

Alright then- thank you for the confirmation. I’ll likely cut it and patch it when I’m done.

it should not be welded, Jaguar never welded exhaust system parts. You should be able to spray a penetrating oil and rotate it off of the over-the-axle pipe.

Old fuel tank is out, new is in, and car is back on the road! I removed the resonator and heat shield to access the necessary bolts. Not a bad job once you know what to do. I did end up cutting the exhaust pipe after penetrating oil, twisting, hammering, etc. did not succeed in loosening it; a welding shop will fix it for about $40. I wanted them to check on my hangers as well (exhaust vibration seems a bit much) so two birds with one stone. Overall was pleased with how well the car came apart and went back together - elegant design!
