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.

Easy to install with good directions included. The provided security bit is nice to have but I installed 4 kits and the bit stripped out twice.

All the parts were in package we needed, although we needed to go the hardware store for cable clamps to secure the ends of cable. So far we feel better about leaving our car in the parking lots.

Cannot install on a 2009 GMC Sierra as designed. Also no instructions in the package. Dual tail pipe into single converter as one unit. Will require some modifications. Have to look at it.

I bought this product for its intended purpose, to protect my catalytic converter from being stolen. Installation was pretty straightforward. The clamps and the cable were great quality. These are definitely a deterrent in a sea of cars and trucks, I feel sorry for the guys next to me who don't have these. Get yours today, you won't regret it later, at least I won't.

Very nice product took a little longer than expected? Because I put it on my RV and one end was difficult to put cable through frame?? But got it done and now I have a little more piece of mind!!

It's a great sense of comfort knowing that I have protection on my vehicle. Although it's only a deterrent, I feel better knowing that a thief may pass on to another vehicle and save me the expense of having to repair it again. My CRV catalytic converter was $1040 dollars plus change to replace. However I can provide a deterrent is fantastic.

The device appears to be well made, even though some of the welds are rough. The webpage images show a unit with clamps painted red, and having half round guards covering the threads where they are exposed between the clamps. The unit I received did not have these guards, and none of the parts were painted. Oh well, the heat would probably ruin the paint anyway. As long as the thing works, I'll be pleased.

Installed on my excursion. Was a little difficult but that was expected in finding ways to tie to the frame. Did it myself. Looks like a good product. Well built.
