No, the CatClamp® kit is attached to the frame of the vehicle up to seven times using tough to cut aircraft-grade wire rope.

On a vehicle without a frame (unibody construction), the anti-sway bar and/or engine/transmission brackets are utilized as durable attachment points. The Patented CatClamp® design requires only a 3/8" hole/opening for the wire rope to pass through and secure the CatClamp® to the vehicle chassis up to seven times.

One CatClamp® kit is recommended for each catalytic converter you wish to protect. If your vehicle has two catalytic converters, you may require two kits.

The CatClamp® can easily be installed by anyone with basic mechanical knowledge. Installation is much easier on a lift, but many customers install the CatClamp® without one. The installation tool is included. Average installation time for a CatClamp ® kit is typically ~60 minutes.
