Glass Packs

Cherry bombs are too loud IMO but I suppose back in the day it was legal versus running straight pipes with no muffler. Id Run a Turbo, Flowmster "Walker Dynamax etc. But that is my preference. If I remember correctly those glass packs end up burning out the glass filler and end up essentially as a resonator. On a car with catylitic converters they run quieter because the CAT serves somewhat as a muffler also. As previousl;y mentioned yes you hear them on ratty old pickups,and they sound like chit. Ever her a loud old truck? it doesnt sound like a performance engine at all LOL!
