Gibson quality, good welds, can tell its well made. A little louder than I thought it would be but works well

This glasspack is awsome!!!!!!!! Sounds sick on my Sierra 5.3 .I am really impressesd. Nice tone at idle, when you get into it it really sounds sweet. doesn't have that annoying drone while cruising around. I highly recommend this glasspack.
