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. 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.

No one has stolen my catalytic converter.

Easy to install. We wound up cutting the very long excess wire and soldering the ends. I was worried that using the zip ties to tie up the excess wire, if something happened and they broke while I was driving, they could damage the underside of my vehicle.

The install was easy. we have installed two of these so far. On a sedan the install was a lot easier than on a truck. On the tuck the cables interfered and came in contact with a cross member. we could not find a way to install without contact with the cross member leaving us with a feeling that rubbing, wear and possible noise may be an issue in the future. Other than that it has been a pretty straight forward install process the true success will be if the vehicles do not get their CATs stolen anymore.

I had our mechanic install the converter guards. He said they went on without a problem and would definitely act as a deterrent to thieves trying to cut off the catalytic converters. Thank you for a great product.

This is a very well-designed, high-quality product! I only wish I would have thoroughly read, (and reread), the clearly written instructions prior to installation. Doing so would have resulted in a better and quicker installation.
