no malleting Basil, all the parts fit together very precisely and easily, allowing for adjusting as needed. I wore clean fabric gloves so I wouldn't spoil the shiny polished parts! (sorry if that sounds ridiculous but I'm a perfectionist).
I raised the car, placing a concrete block under each tire to get max height, then placed supporting jacks front and rear, then I slid under on a mechanic's "dolly", and started attaching and aligning the pieces starting with the front down pipes at the manifolds, inserting the *clamps over the pipes but not tightening them until everything was right and aligned.
*Clamps: the hardware kit included stainless steel clamps but they were the "U" "Midas" muffler shop kind which crimps and distorts the joints as they are tightened and make it impossible to separate the parts later. I did not use them. Instead I ordered Flat Band polished stainless clamps from:

Band clamps allow for parts to be separated in the future. Jaguar never welded exhaust systems, they used Band clamps and "Firegum" exhaust adhesive/sealer. Firegum is not available in the US, but Permatex makes a similar product.
Unlike other stainless exhaust systems, Bell does not cut the long pipes in two for "shipping purposes", everything is made just like the original Jaguar system which minimizes clamps. If there was a hook hanger welded to the original part, it will be there, in stainless.
With 5 mufflers in my system, I expected the S type to be as silent as my XJ-6, but no, the Bell S type exhaust sounds throaty like a XK-120.
