 Well since the rad is enclosed and shielded  by the duct you can probably
wiggle
 a couple of exhaust pipes back down and under along the left side of the
 nose gear behind the rad. I'll see if I can do it in 3D. I forgot....
 are you doing a turbo or NA?

 BTW the aero bending load on those venetian blind cowl flaps is

considerable

 so they should be carbon fiber on either side of 1/4 inch high density
 foam or plywood.

I have decided to do my turbo this way. I can think of no disadvantages
and one major advantage  is the back of the rad is totally unobstructed.
