How to Install a Catalytic Converter


Installing a Catalytic Converter

The Install Process

1. Jack up your rig so you have ample space to work underneath. Spray lube on your cat’s connecting hardware and loosen it up with a wrench.

2. Remove the old catalytic converter. If you have to, break it off with a hammer. But be careful not to rattle the rest of your exhaust.

3. Align your new cat with the factory bolts and tighten. It might help to have someone hold it in place so you have both hands free.

My 2015 Toyota Tacoma TRD Off Road Access Cab 4x4 offers bed space to camp in, haul my dirt bike around, and it's been done up to take on the trails. Favorite mods include my Icon coilovers to soak up the bumps. My Walker Evans 501 Legend wheels wrapped in Toyo RT tires give me the clearance from my upper control arms to fit (and they look darn good) and the over-sized tires take on rocks with plenty of traction. My Rigid Industries fog lights have kept me out of a ditch or two when night wheeling. Growing up going to car shows and helping my dad work on the family vehicles ignited my passion. My best memory was the first time I flushed the coolant. My dad forgot to tell me to keep my face out from under the drain plug. Never made that mistake again!
