Paul,
Here’s a picture of my 20B Cosmo
exhaust inserts. They are different from the N/A splitters in that there
is a “shelf” across the top with a passage feeding into the EGR
system. You can see how much of the port is restricted by the shelf.
So, my impression is that these inserts are designed to reduce emissions,
although they may also reduce db’s too. The turbo inserts
don’t have the shelf, or the splitter. They were a bear to remove.

OK...makes sense to me now. I didn't realize the Cosmo
splitters were different than the NA. Thanks for the explanation.
Paul Conner, flying tomorrow (temps should be around 80 degrees and sunny in Mobile, AL).
Maybe I'll look across the bay and see Rusty in the air.

Hope we are talking about the same
thing. My Cosmo (and 20B) housings had exchaust port inserts that diverted the
gasses on angle to the turbo. The inserts I installed were straight out.

Hi, Buly.....perhaps I don't
understand. If you removed the splitters from the Cosmo housings and replaced
them with NA inserts, don't you still have splitters? I thought that the NA
inserts had splitters, and the turbo did not? Paul Conner
