Take a good look at the tips. If they're dual tips and appear rather thick when looking in from the rear, then they're glasspack tips. The tips ARE the mufflers. I have them on my 85 and love it!

It's fine other than loud, if it's to loud sure add something back.

huh? Never in my life have I heard of “glasspack tips”
I swear some people make sh$t up for whatever reason. 🤷‍♂️
They do make muffler eliminator setups for C4s-normal exhaust routing minus the mufflers.
