Has anyone heard of or tried Mertop Racing Products > https://mertopracing.com/
They're fabricating/ manufacturing intake and exhaust manifolds for a few car manufacturers, including Nissan.
Wondering if anyone has tried their stuff, especially on RB's? I've ordered a front-facing intake, not for any performance gains but mostly asthetics. I'm awaiting shipment so haven't yet seen the finished product and quality. Fingers crossed
