Thanks.
Header pipes are the same, so it's all in the chamber - which is smaller and a more traditional shape on the 2103 compared to the big volume 2072 chamber.
Couple of cosmetic changes to the header at the connections, but length and curvature are identical.
See pic - (ignore Arrow branding, it's the same pipe).
