1.  TOUGHNESS:  The Catclamp is primarily window dressing.  The only part of the Catclamp that is actually securing a catalytic converter to a vehicle is a single cable.  In contrast, The CATCUFF utilizes 6 stainless steel aircraft cables to permanently lock your catalytic converter to your vehicle. 

2.  NOISE:  The Catclamp is prone to rattling and annoying vibration noise.  The "spring feature" touted by the makers of the Catclamp was actually a retro-fix item in response to customer complaints with regard to the noisy nature of the Catclamp.  Even with the "spring feature", the Catclamp still produces audible vibration noise while driving.  The tight-fit design of the CATCUFF, in contrast, creates a snug interface with your catalytic converter that eliminates all vibration noise.

3.  DESIGN:  In simple terms, the CATCUFF is a better designed product than the Catclamp.  Rather than build-up a costly (and rather unnecessary) cage portion thats only purpose is to allow a single cable to protect your catalytic converter, the CATCUFF protects your catalytic converter more directly, with 6 stainless steel aircraft cables that tightly wrap around your catalytic converter.  This simple, yet effective design allows for the most distinct advantage of the CATCUFF: 

4.  PRICE:  At $69.99, the CATCUFF is priced $200-$270 less than the Catclamp.  We at HUTCH Technologies feel that at $69.99 and with even more thief-thwarting toughness, the CATCUFF is priced in proportion to the cost of replacing your catalytic converter and related exhaust piping.  Paying $270-$320 (plus $30 for shipping) for a Catclamp is like buying a $150 lock for a $250 bicylce!  It simply doesn't add up!!
