Cheap Muffler Repair? So I was driving to go get some food today on my lunch break and I noticed that my car seemed a little louder than usual. They all of the sudden the noise changed from a low rumble to a thunderous roar. So now I need a new muffler I'm guessing. Hopefully its not any closer to the engine than that. But anyways, does anyone know cheap place to get a new muffler? I'm not looking for quility here, just price. I plan to get rid of this car as soon as I graduate in December. Any suggestions?
