Seven Kit Car - K20 Exhaust Manifold

[20Drift]

Evening all, currently building an MK RX5 with a K20 engine. I held off purchasing their exhaust manifold offering, as a few people had complained about fitment issues, and after seeing one in person, I didn't feel it was worth the cost.

Has anyone got a recommendation for a stainless manifold fabricator near Surrey (within 90 mins of Gatwick)? Ideally with experience with K20 engines. I did speak to Kevin at Zero Exhausts, but he's booked until July at the moment, so hoping there's someone with availability slightly sooner.

Thanks!
