It's bad enough that they dont look even under the car? but they are quiet as fuck..
what is the deal? will they be louder if the pipe is more narrow? or will that give them a higher pitch?
I was told that the shorter glasspack's are louder, so I got some short one's on my 68 and they are not as loud as what
I have on my 76!
Is it true that if you put them on backward's they will be louder?
I used to hear a rumor that if you spray water inside them it does something to make them louder?
when I was a kid they used to call glasspacks (RAPPER'S) because of the loud rapping noise they would make when you accelerate or downshift..
