I have been asked the question about making extra discs for the Boss.
I cut discs out of aluminum stock to test here but they are not for long term use.
http://forums.themustangsource.com/f813/experimenting-exhaust-discs-494329/
Update: As many know I have made many of these discs and still have them. Sizes are 1/2, 5/8, 3/4, 7/8 and 1 inch. One set shipped is $27 two or more just add $18 each, no extra shipping charges. Any questions please email me -- sjrsw (at) yahoo.com

Jack up the car as shown below, be careful not to put your arm in between the jack when reattaching the rocker bolt while underneath, it is easy to do and you see what I mean when doing it. If the piston ever gives way....
You will need to go just a bit forward from the jack point in the picture for the rear side pipes but that is fine, no damage worries. Just stay centered on the pinch weld, the rocker bolt is near the jack point in the picture. Otherwise loosen the rocker bolt before and after but that will make it a little harder to adjust. It is best to get a rubber pad for the jack, you can get them anywhere, I ordered one from harborfreight tools and it works great.
To install the Boss 302 exhaust discs you need a 15 wrench and a 15mm socket for the rocker bolts. You remove the three bolts/nuts circled, drop the pipe, pull out the old discs and install the new discs. Make sure the adjustment band on the side pipe has clearance from the floor or it will rattle. You will need about 3/8 of an inch or a little less then a finger width. This is made easier by first installing the rocker bolt but do not completely tighten it until you are finished adjusting the pipe.
If you are unable to get a good clearance with the floor or the pipe is not level (mine was not adjusted correctly from the factory) loosen the long bolt on the band and twist the pipe around a little, that will level the pipe and adjust clearance to the floor boards. As always email me with any questions.
