Header attachment question

[DavidZ]

I've been looking at pics of stock and aftermarket S65 headers, and it seems the only attachment point is from the header flange to the cylinder head? There's no other attachment point? I ask because I installed an x pipe (aFe) and like many aftermarket exhaust parts, fit was not 100%. The x pipe is slightly pulling the headers inward. I doubt it'll be a problem but was wondering if any extra stress is going straight to the bolts in the cylinder head?

TL/DR: do the S65 headers attach anywhere else besides the header flange to the cylinder head?

They do not

I have a BW and a ESs xpipe and both fit perfectly fine

I know of a couple of cases where additional weight of custom exhausts have, over time (about 6 months), stressed the manifold and stretched the bolts. The cylinder head bolt holes can't be increased in depth or diameter so a flexible accordion-type section of pipe was installed to absorb the weight and stress of the system.
