Rattle in stock y-pipe?????
Could the cats be coming apart???
If so it's time for headers
I also noticed that I have a rattle near the gas tank. If I bang on the hatch area above the tank something vibrates, it also does it if tap on the tank form underneath. The tank strap bolts are tight .
TIA
My exhaust is completely stock with a 3.5" cutout. I'm just going through the entire car to eliminate some rattles and squeaks.
Everything is tight under the car.
If that is similar to yours, its more than likely one of both rear 02's. Could always just take them off and bang on the y-pipe and see if it still makes the sound to eliminate them as being the cause. Good luck.

It only makes the noise when I bang on the y-pipe with my hand. Since I don't hear it while driving I'll leave it alone.
Mine does this as well. It will do it if I bang on the Y-pipe by hand or even when sitting idling.
My O2s are tight. So what about them causes it?






haha what is that stapmed piece of brace under the car for anything?
