Practice mufflers

And the stocker next to the "Super A-body" mufflers. Stock ones are 18" long by 4.25" or so by 9.25" or so with 2.25" in and out bushings that are about 2" long.
The new mufflers are 19" by 5" by 11" and we shall keep the overall length close to 22.0" by welding the three bolt flanges where needed.
