Opinion On MSA Exhaust Equipment

[FastWoman]

Only when dropping down from maybe 4500 RPM.  Some people like light afterfiring, but I hate it.  It doesn't happen often, though.

I'm not back for long!  I came to beg favors from a few people.  When I logged in, the message popped up that someone had asked me a question.  Unfortunately I don't have any time for my Z these days.  I've been drowning in other areas of life -- my partner dealing with cancer, and now this new health care bill (in the US) that threatens her health care future.  This is OT on this particular board, so I won't go into details.  But that's why I'm back -- for some private messaging.  (Sorry!  Life gets in the way, as they say...)

I miss you guys!  I miss working on my Z.

Getting back on topic, I don't think the afterfire would have anything to do with the exhaust.  I think it has more to do with the idle enrichment (at zero throttle) when the RPMs drop back below maybe 3000, the point at which the EFI starts injecting again.  I have no idea why the exhaust pop only happens when I drop from 4500'ish, though!

Gotta run...  Oven timer went off.  Dinner!  :-)
