Hi Tuomas, you going to Switzerland?

My Hatori kept coming loose right at the exhaust outlet. Tried locking it with all sorts but none were high temp enough. Tried wrapping the thread with PTFE tape that worked for a while, then it came loose. Wouldn't be such an issue if the big nut was accessible but you have to dismantle the whole thing to get access to it. Real ***** design if you ask me.

Unless you can find very hi temp thread locker then I would advise you stay well away from the 822 header.

As for the Asano I’ve heard that there were problems in that "the nut was very easy to bend out of shape. Also the flange on two headers broke". And these guys are far from numpties, so if they are having problems you can be sure there are others having problems as well. No way I'm spending >£90 for a manifold that may not work.
