Hi All,
I sincerely hope that my post does not contravene any written or unwritten rules on this site.
I purchased a rebuilt 1994 Tbird M90 that I intend on installing into a, gasp, Mustang. It had the silencer ports blocked off by an aluminum plate.
In all of my research, I have never seen this method employed before. The majority of blocked off the ports used either JB Weld or they were welded shut.
Before installing the blower, I would like to solicit some opinions on this subject. Just how much louder will this be versus open ports? If I do decide to keep the plate installed, I would make sure to use hi temp thread locker on the three bolts holding the plate on.
Any and all input most welcome.

I'm not sure the DB levels but it will be a shade louder with the ports covered. If you really want to hear the blower whine change the intake and or IC piping to thin aluminum tubing.
