Trying to pin point a noise coming under the car, sounds more near the firewall but not sure. I know trying to explain a noise online is stupid...but im stuck and looked everywhere and cant make the noise unless the car is on.

Noise will appear when in idle and accelerating. Cant really hear it after 3k rpms. The noise sounds like a bearing but at the same time it sounds like a loose pulley if you know what i mean. Ive checked the bolts on exhaust and nothing. Ive tried to listen to it from the engine bay and cant really hear it. Its gotten ALOT louder in the past week. I haven't added any mods or anything it just came out of no where.



****Replaced the cat with a test pipe and noise is gone..


Thanks, and let me know if theres anything i can do to help figure this out, dont have time to take to a dealer or anything for a week or so ...so im trying to do this on my own time at home after work.
