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.

Fully stainless steel construction is the secret to the success of the CatClamp Ant-theft Cage Device. 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, Toyota Prius, 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. Compatible with gas and small diesel engines.

We’ve had vehicles with cat clamps and those without. The vehicles with the clamp are not tampered with while we still experience theft on rose not equipped. I just made a purchase of ten more clamps to protect my more vulnerable vehicles.

Overall the CatClamp is a very easy to install DIY friendly product. Really happy with the results and the amount of protection it provides. Also there’s plenty of cable length wise, I was able to protect both my CCs with the cable and hardware provided. Well worth the cost and time to protect your expensive and targeted CCs. I highly recommend the CatClamp.

We were sold a product that could not perform as specified, and Auto Accessories refused to allow us to ship back for a return. Incredibly disappointed in this company and suggest you do business elsewhere.

For my vehicle the wire was to long so I just cut some of it after it was all installed, I think it would definitely take longer for someone to steal the catalytic with this cable around it, overeat everything looks good I just don’t it is worth the money.

I bought the Cat Clamp Standard. It took just over an hour for my muffler guy to install on my 2010 Honda Accord. He could not install the screw bolts as he did not have the exact star bit to fit it has a larger post than his standard bit possessed and had to grind a slot to make it a slotted screw to tighten. So it might help if Cat Clamp provided a cheap bit to help with the installation. The cables could not really attach too much more than the exhaust pipes, so I am not sure if it will deter the most dedicated thief.

To all concerned:....This product is a decent design....no, it's not 100% proof that it can keep that converter on your vehicle, but it can certainly slow the thieves down...a lot...I think it's priced too high for the parts that you receive, but in today's world everything is too high....I feel better that I have it installed on my Class A Motorhome and I like the concept that it is a open design so the converter can still perform as intended and the heat around it can be dissipated....some covers I have seen may cause the converter to run too hot....but only looks that way as I have not seen any test results from them...so, I would still recommend any one that is interested in keeping their converter on their vehicle to compare this to other methods and decide for themselves if this is the right way to go. For me, I have it installed and will also install some type of alarm system to further deter theft. Also, I add nuts to the ends of my security screws and will weld them onto the clamps...going to be a lot of work to try to remove it for sure.
