Nah no cat...
I tried checking it out today..it was bad coming home from school but then i came home and me and my friend hand tightened a bolt that connects the downpipe to the resonator. The scraping is like almost gone but it still is faint.... i think a gasket somewhere along the exhaust system is bad or something. The metal squeek sounds like a belt, but im not sure which one...

Anyone know the costs of exhaust manifold gaskets and like other gaskets??

Does this sound like it could be a problem?
