bullets glasspacks or what

Well, I know the loudmouths have no packing in them at all. My magnapacks are more like glasspacks except the magnapacks are packet with stainless steal mess not fiberglass. Fiberglass will blow out over time in the glasspacks but the steal in the packs wont. I don’t know about the bullets.
 
there was some clips of glasspacks on mustangexhaust.com and they sound pretty good,they somewhat sound very close to Maganapacks...the Dynomax Bulletts do sound badass tho, similar to my LM2 and theyre cheap!
