Glass Packs

When I first set up my 64 Barracuda in the early 70's I put the 65 Commando system in from Maremont. 2 1/2 straight thru muffler and 2 1/4 straight thru resonator. Great sounding exhaust system that was quiet enough for a daily driver, cross country trips, and would sound like NASCAR when wide open.
I took the resonator off once, took a short drive, and put it right back on. Glass packs are not the same, I always thought Cherry Bombs were the best. I hated Thrush glass packs.
