Thats the one. You can get them unfinished in bare steel. The old schoolers used to fill them with water and the glass would break away and shoot out the pipe. The same thing will happen over the course of a couple months regular driving. Having heard glasspacks as opposed to straight exhaust on several dif hotrods I can tell you there is a def difference. The glasspack makes the car first of all legal and second does provide some muffling. Not alot but there is no mistaking a straight offroad exhaust with no muffler.

Remember that the glasspack is not for someone looking to add a little rumble to their truck. It is loud. Not ricey but loud. Don't pm me later and say this is way too loud for me. How could you reccomend this. Anyone switching from the stock muffler to a glasspack will be rather shocked at first. But the sound is nasty!! Not overbearing but deep and nasty. I love it.
