All of my exhaust manifolds are junk, or at least suspect ("I found it was warped so I had it machined flat.. the flange is thinner at the back, but I just use a washer under the hold down to compensate"). Since I eventually want to go turbo I decided to get a SPA manifold and get it over with. Got my funds lined up and...

no manifolds. None. None anywhere as far as I can tell.

I understand this is part of the big COVID / shipping mess etc. But does anyone have an idea when more will be available? I have some time (robotics season absorbs all my time until May) but want to get going before 2023.

We have them in stock.

BTW I have coached FTC robotics for many years. Our teams usually did very well. Fun stuff to teach the kids.

I swear it showed out of stock last time I checked. Ordered and paid.

Robotics, my FTC team won our first competition and qualified for the Michigan State championships. Competing again this week then States in 2 weeks. I also mentor an FRC team, the Fighting Pi, and judge FLL.

You meet the neatest people here and in robotics!

Delivered. Thanks Tom!

Side note, FTC team was #1 qualifier in our division, lost in the division finals due to partner's penalty points. Great run by the kids.
