Re: Cat Question
Check for o2 sensors. If there are ones after teh cat, then removing them is going to bring up a trouble code. It IS illegal to remove a cat from any truck that came with one from the factory, so if it was my truck and i wanted to get rid of it, i'd do one of two things.
1. Remove cat, and punch out all the honeycomb stuff wiht a BF screwdriver. Break it up and shake it out. Then reinstall
or 2. Break up insides of cat, and push exhaust tubing through it, and reinstall.
These ways, it will be a lot less obvious to cops/inspectors that you have dissabled your cat.
But remember, you won't pass smog without a cat, so if you remove it completely, be prepared to reinstall one/purchase a new one when smog check time rolls around!
