Greetings,
I have searched but cannot find a DIY for replacement of my 1990 exhaust. Does anyone know where I could find one?
Thanks for helping the noob!

 

I doubt you'll find one. It's basically crawl under car, unbolt/cut old system off, install new system.

For exhaustsystems I prefer the muffler shops as the parts are usually rusted together and you need a torch or saws-all to get the old system off. You may also need some welding to
re-install some parts that don't need replacement.
