Howdy!
I want to buy an exhaust kit for my 1982 c20 350 long bed but can only find kits for offset mufflers (Flow Masters, Thrush Turbos, etc. ) but I would like to install glass packs. Does anyone know where I can get a kit for straight through mufflers or and modifications you have made to an offset kit to fit glass packs? I hope this makes sense
Thanks in advance!

Get the kit for offset flowmasters and run these.

They are straight through perforated tube mufflers(basically glasspacks), but in an offset configuration. I have a straight through 3.5" one on my Suburban right before a Flowmaster 50 series to help with resonation and they are very solid construction.

Do those sound like glass packs? I’m really going for that bark you get from a glass pack. Thanks for the information! These might be my next purchase:D

Glass packs are available as offset in/out, you would need to verify pipe diameters and lengths etc of course.

They are literally glass packs. They are a straight through pipe with fiberglass packing around the pipe. You will get a bit more interior resonation reduction with the bigger case of the pypes, but it is still a straight through muffler. Here's some clips of real world sound with dual race pros.

I even think they still make the old Thrush mufflers, and those were pretty straight through design.....
