Catalytic converter

I would bet that most cats stolen are on storage lots. Sure they may have cameras (which are about worthless) but at 2am, there is no one around to hear the sounds of banging, grinding and cutting.

Our friend had the CC stolen off her RAV4 in a parking lot right in front of the Panera restaurant they were eating at. It was the second converter stolen off that vehicle in just under a year. Her husband ordered two Cat Straps the next afternoon after I gave her a link.

The solution is for vehicle manufacturers to make it harder to just make like a worm, crawl under, and have unobstructed access to the cat.

Look at the vehicles that are victimized. Most have easy access to the target.

What's puzzling is how manufacturers have no problem hiding relatively inexpensive items that need periodic maintenance or repairs but can't figure out how to make cat converter just as difficult or impossible to reach by a thief.

Those things get HOT! 1200 ºF ! How much other stuff under the hood gets baked and fails (electrical connectors, wire insulation, plastic brackets, plastic wire looms, drive belts, hoses for A/C, coolant, vacuum, and fuel) due to the extra heat.

My daily driver is a 2006 Tahoe. DW's former vehicle was a 2006 Yukon XL, essentially the same vehicle. Both vehicles have converters very close to, and directly connected to, the exhaust manifolds. They heat has baked off the plastic heater-hose connectors, failing so frequently that Dorman makes aftermarket replacements. The underhood electrical connectors are fragile.

GM puts cowlings all around the engine. On DW's vehicle, when I took those off to change spark plugs, all of the flexible wire looms just crumbled away. The only reason it didn't happen on the Tahoe is that the state Highway Patrol garage had taken those cowlings off and thrown them away.

Might just be a GM issue. My truck is 19 years old and spent most of it's life (130,00+ miles) towing trailers.

Underhood does get hot but still seems to get enough air circulation to keep heat damage down.

All wires are OE other than the wires I've added for trailer battery charging.
