    Default Suzuki GV decat

    Hi All

    I will be doing a decat on my 2012 Suzuki GV this weekend. I have bought a O2 fooler and will be knocking out the honeycomb from the original cat and fit it back in. I will post my process and findings here.

    So the deed is done, and the good news is: No engine light!

    What I did was take the elbow bend off the bottom of the Cat. This is the joint where the OČ sensor screws in. It would be easier to take the insides out if you removed the whole Cat, but that means taking off the headers and such, which was outside of my motivation today.

    I then fashioned a funnel out of cardboard box and placed it under the cat. Safety precautions I took were garden gloves and a dust mask. Apparently, the honeycomb is pretty toxic.

    I used a combination of a crowbar and hammer, and drilling holes in strategic locations. The beginning is pretty tough to get going and pretty dusty. It's a very fine powder that is created. If you have the cat completely out of the car, I am sure you'll be able to break it out more in chunks, the limited space under the car made for akward positions. About halfway through, I decided to jack the car up and put it on Jack stands to get more space. This worked quite a bit better. After all the insides were outside, I added the fooler to the elbow joint and put it back in. The OČ sensor is easier to take out and put back in while the joint is loose. Also, remember to pre twist the wires anti-clockwise before putting it back in, as you'll have to tighten it.

    Initial findings:
    - Not a super clear power gain...wasn't expecting much
    - The car sounds pretty much the same
    - There is a bit of a smell now when the car is standing still. My nose is not the best at smelling, so it is fine for me, but I can see how it could be a problem for someone who has a sensitive smell
    - I just filled up a new tank. My previous odometer average in city was 7.7km/l - 8km/l (I have a raise and bigger tyres which negatively impact me) I will monitor my consuption on the new tank or two to see if there is an improvement.

    What would I have done differently:
    - Set more time aside and remove the whole thing, I think the removal of the insides will then be way easier and less messy OR just jack up the car pretty high from the start of that is not an option
    - wear eye protection. Full goggles that "seal" your eyes...it's very dusty
    - wear long sleeve clothes. I was skidding around on the floor under the car, and am now a bit itchy. Similar feeling to fibre glass itch on my fore arms and backClick image for larger version.

    **Update: I recycled the Mesh at AST recycling (https://astrecycling.co.za/) and they paid me R1300 which is not bad. that is ~R900 profit after the fooler purchace (https://www.takealot.com/car-oxygen-...e/PLID91668608) This will go to my Rock slider fund
