havent been on for a while but i found a broken down festiva in a high school auto shop and the teacher is letting me snag parts off of it. one thing is the exhaust. who ever had mine used cheap tubing and it broke warped and dont unspeakable things to the metal but instead of fixing it they put on connectors that didn't quite fit so it rattles and makes very loud obnoxious noises and i need to fix it in fear of damaging a valve. i was thinking of taking the whole exhaust system off and putting it on mine down to the heat shield. so i was wondering if there is any issues i should look out for? and another thing ive noticed i have a half sized radiator, whats up with that?
