It will work on the Vipers and SRT10 Trucks. It will not work on the Hemi, new Electronic Drive by Wire TB vehicles, or NGC computer vehicles.
If you just remove the cat, and possibly the post cat O2 sensor you will get irratic idle, loss of performance, and a never ending MIL light ...
We have the answer! The Post Cat O2 SIMM ! This device completely fools the PCM, it thinks you have a very efficient CAT installed. Simply replace the post cat O2 sensor with this device.
The circuit board is computer grade fiberglass / epoxy, all of the components are MIL Spec, close tolerance. The board is installed in the high impact ABS case then potted with high grade epoxy. This makes it totally vibration proof, and extremely moisture resistant. This yields a device that will work from -50' F to 250' F ...
This part also will correct the problem of the Check Engine Light when the stock Cat is replaced with a Highflow Performance Cat.
