Day 1 & back to Day 2 Exhaust.....

[Day2_69Z]

Text book Day 2 ?
The Old Magazine Ads are "text book" .....2 1/2 inch is a good choice as is the Transverse H.P. muffler.....Walker & other exhaust companies had a master interchange / available application with dimensions of mufflers available as substitute/upgrade replacements in the index are
(Back of catalog) a lot of guys back then put those Hemi type or HD truck mufflers in place of transverse or resonators......to avoid glass packs altogether.
I removed the Chambered exhaust & went Vintage aftermarket Duals to show off the details of the rear under carriage and to mount the NOS vintage Holley Blue pump to the floor/frame kick up .....instead of in the "trunk" oops.
