The latest batch of OCs have this extra black material under the
engine. Anybody knows what it's for?
Today - 44J & 45G on 171, 46D & 47B on test, 48Z on 811
S1
I'll attach a couple of photos of the black material, hope
somebody can shed some light...


no. notice e exhaust pipe dosen't face e back directly like 1H
if u noticed.
i believe that thing is used to cover e exhaust pipe so e
exhaust fumes will go out by e right.
