16v header for A2/ MK2 , with small aftermarket cat with o2 bung. Unsure of the maker (if i was to guess I would say eurospec, it isn't TT) but is a
real nice one, and has very little use. 46mm primarys, 2.25 outlet. Has a flex joint, etc. the cat is small and gutted, prob a fake one for emissions somewhere else. Is pretty beefy tubing and would be a good street header.
