I'm Awesome
I installed a thrush welded on my 94' GMC and took it off 6 months later. lol It was deffinetly louder then stock, had a nice rumble at cruise and was throaty under hard acceleration. But the drone in the interior was pretty annoying. I mean it wasn't horrible, but my set up now is 1000X better. Granted i have a 350 not a 4.3, I would still say go with a glasspack. There one of the oldest "perfromance" mufflers out there. I currently have a 18" Glasspack with a 3" exhaust system and my exhaust tone is perfect to me. It will scream under acceleration and has a nice rumble at cruising RPM's. And best of all ZERO interior drone!!!!!
