I took it to the place i got it at and they said it would be $700 to replace it. My auto-tech teacher said a high-flow would cost around $150, is that true?

Just get a test pipe to replace the cat if you dont have emissions checks. Theyre like $50 on ebay. If not then yes, high-flow cats do cost $100-200...

1. Check the heat shields first, I've had a few rattling. Bend them if necessary.
2. The cat has a heat shield as well. Mine rusted and started rattling. Fix: tore off the lower half of the heat shield. I didn't feel it was completely necessary to protect the ground from heat.
3. Check the resonator on the mid-pipe. The welds around the ends of it will rust through over time and start rattling.
4. Check hangers and rubber dampers.
