Hey Z1. ETA on those headers?

This mod just blew up overnight with short supply. Just know Z1 will provide a great product that's trouble free.

To that point, I think the Momentums were very oversized for the engine they were originally designed for, and have a very nice collector design, so I'd be pretty surprised if other 35DE headers get any gains. A lot of them will absolutely fit (I tested some DE long tubes, fit fine with only minor adjustment to a heat shield needed), but they were awful, performance wise.
