Re: minimize radar signature side exhaust

What frequencies? A possible device is a mesh/quarter wavelength deep - but
the design requires a knowledge of the frequencies to be blocked.
search net for F117A air intake analysis

Alternatively dog-leg the pipe and line the inside with radar absorbing
material - search for "Radar absorbing material"
