Industry reports say that the average catalytic converter thief needs nothing more than thirty seconds and a battery-powered saw blade to strip your vehicle of its converter. Usually containing palladium, platinum, and/or rhodium, a stolen catalytic converter can fetch thieves a pretty penny, not to mention cost you up to $1,000 in total repair costs to get it replaced. Protect yourself by neutralizing that saw and prolonging those precious seconds with the CatClamp Catalytic Converter Lock.

An e-coated and galvanized alloy steel construction is the secret to the success of the CatClamp. Nearly unbreakable and impossible to saw with a standard handheld, this rope forms an impenetrable barrier around your catalytic converter. Combined with split clamp assemblies placed on each side of your car converter, this system keeps your converter safe. Split-collar cage ends allow this herculean rope to pass through it as many as eight different times, and the collars on your Toyota 4Runner or Honda Element catalytic converter lock, or those for whatever vehicle you own, make sure everything stays in one place upon tightening.

Upgrading to the Cat Clamp MAXX lock gives you even more protection. In addition to everything you get with the standard Cat Clamp, you'll also enjoy 100% stainless steel construction of both split-collars. Don't run the risk of having to foot the bill for an expensive catalytic converter replacement. Make sure thieves will skip your car with the made in the U.S.A. CatClamp Catalytic Converter Lock. Backed by a 1-Year Warranty for the standard Cat Clamp and a Lifetime Warranty for the MAXX.

Will this fit my vehicle? Designed for a universal fit, both the Standard and MAXX Locks are designed to fit common catalytic converter pipe diameters of 1.75” to 3”. These locks work best with 3” of available space around the point of contact for each of the two clamps. Not compatible with diesel engines.

Installed by the mechanic who replaced my stolen catalytic converter for the second time on my Honda Element. So far so good, my 3rd catalytic converter is still in place 4 months later. I was worried this device would be noisy based on some reviews on other sites but I haven't noticed any noise at all.

I went to several muffler shops to see if they would be able to put the device on for me. Many of the shop owners had never installed a clamp before. I located a muffler shop owner, who too, had no idea how to install, yet he said he would try. It took a while because he said the cable wire had to lock in (I guess that was the language he used), but after a few hours they put it on. I was not upset, due to he and others never putting a clamp on before. I'm only giving four stars because so far, I have not had an issue since it's been installed. I hope and pray this is the deterrent needed to keep from having to replace another converter. This was the second converter I had stolen. As a plus, the turn around time for ordering the clamp was A-1. Ordered on a Thursday around midnight and received it on Saturday morning. It's still too early to say success, but please don't let this deter you the customer from purchasing one.

I had one of these installed years ago on a 2001 Toyota 4Runner. The setup does look intimidating to a thief. My cat has not been tampered with so I would say it's doing its job. I had purchased more for my other vehicles when some thief attempted to steal the cat on my other vehicle. They failed because of a broken saw blade and a neighbor leaving for work in the early in the morning. It is an insurance and it can be removed if any work needs to be done on the exhaust system. It's a good deterrent.

My mechanic installed it and it took him two hours. It is not visible, but as long as it keeps the catalytic converter protected and prevents it from being stolen, then it is doing its job.
