quoting from Maxxfab site:
"These housings have the same features as the OEM replacement housings decribed above, but have the pentastar shaped Stage 3 flange needed for installation to the Stage 3 exhaust manifold.
The inlet to the O2 housing has been expanded to approx 3.75inches in diameter to take full advantage of the exhaust opening in the Stage 3 exhaust manifold. The exit end of the O2 housing is 3 inch in diameter. This allows any aftermarket exhaust to bolt right up the the MAXX Fab Satge 3 O2 housing."
