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.

The cage itself is pretty sturdy and seems legit. Installation took about 40 minutes.

Purchased the unit for my granddaughter’s pickup. Directions were easy to understand and the clamps fit perfectly over my exhaust system. Threaded the cables through the clamps took a little planning and some thought but it worked out well. I’m happy with the unit.

I bought a pair of these for my 2012 Toyota Tacoma after my local Auto Repair shop had one of their techs swing under my truck to conform that I had more than one Cat Converter. They recommended I obtain the Kits myself and bring them in to them for installation. So, I contacted AAG on recommendation of a neighbor and ordered two kits. The Shop put three techs on my install - they were crawling all over my truck while it was on the lift, and from all indications did a really good job. I guess we'll know if we ever witness any thugs (who can't read the "Cat Clamp" stickers on the windows) crawl out from under empty-handed! I purchased and had these installed because I use my truck in my work every day, and the under $600 that the project cost will be recovered in just one instance of protecting my truck from being out of commission for possibly weeks and costing well north of 3 grand to replace the stolen converters! (BTW, here in the Front Range, Colorado area we are experiencing a spate of thefts - so I have to believe I made the right decision.)

Quality product. Installed myself lying on the ground with front tire on ramps. Biggest issue was finding places under the vehicle to route the cables through. Once that was determined, install went well. Routed the cables through rubber hose to shield cable from contacting metal on vehicle to prevent noise. Had extra cable and my bolt cutters would not cut it, so although a problem, it was good to see how tough the cable is. Cut the cable with my dremel and it took a good five minutes to cut it, so again pleased with how strong the cable is. I think anyone seeing the install will leave me alone. Highly recommended. I will install a second one today and it will take half the time as the first one.

I recently purchased the Cat Clamp in hopes of keeping my cat where it should be. I know it may not fully stop a scumbag from taking the cat but hopefully it can cause more of a hassle and just move them on to the next target. I've been a victim to having my cat stolen and to be honest I Rather pay the amount for the cat clamp instead of a new cat any day.

Comes with simple instructions but is easy to figure out. Comes with different shim insert sizes to fit your vehicle. Easy to install. I sleep better at night knowing my catalytic converter is slightly safer from thieves.

Our storage facility was targeted and seven catalytic converters were stolen - ours would have been taken if we hadn’t been on a trip. Definitely worth the piece of mind.
