Anyone ever run these glasspacks???
I ordered these really cheap 2.5" glasspacks that are called "Thunderbolt Glass Packs" and I was wondering if anyone has ever run these and could tell me how they are as far as sound. I got them from this place: http://www.racerpartswholesale.com/tbolt1.htm
Let me know. Thnaks HotRod

Not those exact ones, but they look awefully close to the Flo-Pro glasspacks I've got on my truck. I've got the 3"ers, but my buddy has a big block with 2.5"ers and loves the sound

Not sure what brand mine are, but they are 12" long and sound great. What size did you get, the length will make a big difference in the sound you get.

I replaced mine with new ones when I rebuilt everything. The originals sounded good with the stock exhaust manifolds but I do not like the sound with headders. I am converting to flowmasters as soon as $ permits.
