Glass Packs Revisited

Glass Packs Revisited

For the past year I have been driving the Astre SJ straight off the headers. Around the neighborhood and to get gas once a month or so, not on the road or highways. The main reason I just couldn't settle on a Muffler choice, but that has all changed. I was at a cruise and in the distance I heard what I thought was the sweetest sound I have herd in many years. The car was a MGB with a glass pack. The guy couldn't tell me the brand since he had purchased the car with the glass pack. I looked under the little car and the muffler was red so I surmised it was a "Cherry Bomb" Glass pack.

The reason I mention this is because I associate Glass Packs with my youth and with my age I have become very nostalgic about things in general. This is all to say I have found the perfect muffler for the SJ. I know it's not throaty and all "Big Block" sounding but there that Glass Pack resides in my memory as the sweetest sound of them all.

Anyone, have a suggestion on a favorite Glass pack?

Phil,

I don't think I've had Cherry Bombs (and loud pipe tickets) since the '80s! Nowadays, I seem to be concerned about the fiberglass burning up. I've been using Magnaflow lately, with steel wool packing, and they do make 3" and 4" round mufflers as well as the ovals.

There are also different tones depending on the number of cylinders passing through the mufflers, my first new car was a '66 Corvair and duals on the flat 6 made a sound I can't duplicate today.

The Cherry Bomb Vortex sounds the same as the old standard glass pack , plus it may fit in the factory location on HBodys.

Alot of Cherry Bomb testing on YouTube.

I'm with you Phil, I remember everyone was into Thrush mufflers and Turbo mufflers back in the day but I all ways ran the good ole Glasspacks myself, mainly with full pipes.

I guess it's, "what goes around, comes around"....
I always liked the sound of a Glass Pack but then I got hooked on the metallic sound of Flowmasters which I don't care so much for nowadays. The deal is the ear is a pretty exacting instrument, not like the eye which can play tricks on you. The ear searches for definition. I learned this from music. Ya, a Thrush would be a good second choice, very distinctive. The ill named "Turbo" is just a collective of various sounds under one roof. I've been through probably ten sets of Turbos down through the years and none sounded like the other.

I should mention here the SJ is not ready for the highways, so it may be awhile before I fully commit to a Glass pack muffler.
