Catalytic Converter Heat Shield Rattle Noise Fixed for $5 in 5 minutes with stainless steel clamps

Watch this video to fix catalytic converter heat shield loose rattle noise and secure the shield in the process. You will need to buy stainless steel hose clamps (5 - 7" - Home Dept or Lowes plumbing department), have a screwdriver or socket and ratchet to tighten the hose clamp.

This is probably whats making that raspy rattle noise I hear on my TL as well.

My heat shield was completely loose and rattling… but it was on the top. The bottom is hard steel with no shield… does this mean it’s already fallen off? Mine didn’t have any screw holes. Looks like they tack welded it or something. Also, Harbor Freight has stainless steel zip ties. Probably even easier to use than the hose clamps.

Seems like the bottom half fell off already

you should show people the noise before you fixed it. So it is much better to understand it.
