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.

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.

I purchased this because I was robbed twice with four months even with the alarm on my Hyundai Tucson. The shop who replaced the catalytic converter said it couldn't be done. I was referred to another shop who have done it before and took care of me. I pray this will work.

I won't know how well the product works until the next time (third time) someone tries to steal my catalytic converter. But I can definitely report that the staff at Auto Accessories Garage and at the manufacturer are wonderful -- highly motivated to make the customer's experience easy, pleasant and painless. My mechanics had trouble installing the device due to the lack of room between my exhaust pipe and heat shield (which had both been replaced after a rear-end collision). Heather at the manufacturer walked them through it over the phone and they were able to install it with her help. I can't find enough good things to say about these folks.

I had the auto mechanic installed it a few weeks ago. Despite various YouTube DIY tutorial videos, I rather leave it to the expert. Before the mechanic installed it, he stated that it might make rattling noise while driving but that wasn't the case. I'm pleased with the result.
