I did a search and amazingly I didn't come across a specific exhaust thread. I know our blazers aren't hot rods... But some people like hearing the exhaust even when it sounds like a tractor.
I'd love to start off this thread. But shamefully my exhaust is stock:icon_shrug:. So if anyone wants to put up a video of their exhaust on here. Please be informative about what you have for exhaust...(brand of muffler/model), (size of pipe), (catalytic converter/no cat), and (single tailpipe/dual tailpipe). And also included what year your vehicle is please.

If I get the nasty weather tomorrow. I'll make a vid of my 1992 fullsize with the 4.3 TBI. And my vortec (stock) blazer.

I need to get a new video of mine, my old one was when it was brand new and wasn't broken in.

Plenty of 'exhaust threads' in the Headers, Intake, & Exhaust section.
