Thrush welded exhaust

I recently just welded on a thrush welded muffler on my 1999 Chevy ls Blazer 4.3L 4wd. It still has the cat on it and stock tailpipe. After installing I started it up and it is just as quiet as my stock muffler. Any suggestions? Thanks for the help.

If you want a louder Thrush, get their Glasspack or Rattler. The Welded is in the middle for loudness.
