Danger Dude is right on...I had a '66 F100 in high school (one of the few things about me back then EVERYBODY remembers!) with glass packs, and it sounded BAD. They were broken inside (which is GOOD) and I had a blast racking them off with a stab on the gas. When they would sound off it always sounded to me like Ol' Blue was taking a deep breath getting ready to make RICE puddin'!
Unfortunately, the power in that sound was the massive volume of exhaust flowing through them. Our V6's blow like a flute compared to a tuba. :no:
Glad to hear there's a place here to listen to different tones. Somebody download some glass packs to enlighten the curious!
