Loud and mean??? I've heard some that sound god-awful... and some that didn't sound like the muffler next to it... So then the fiberglass breaks??? whatever they don't sound good IMO... not a very smoothe tone and more like a bee in a beer can...
I've honestly never heard Glasspacks sound very good unless they were brand new... and IMO there not that lound or throaty anyway... Like I said the guy I work with has a brand new Seirea 4x4 a lot like my 4x4 Hemi Ram.. only took GMC 5 years to catch up.. And his Glasspacks suck, he took them off and went with Flowmasters... A la the Hemi....He had his Glasspacks for about two months before they broke... to me they sound like a very poorly made product... I do know there cheap, but jeez...
