I have a 1985 gsl-se. I need a new exhaust really bad and I only have like 300 bucks to get it replaced. the flex pipe but everything else behind it needs to be replaced and actually the car has been parked for awhile and the exhaust is just sitting on the ground well anyways,would just running pipe to a muffle be ok or would my car run shitty

 

First gens didn't have flex pipe stock. Check with your local muffler shop and see what they can do. Don't forget the back pressure pipe to open the auxilary/6th ports.
