Thread: 2.2 TDCi (Puma) CAT Delete

Last year I removed and reinstalled (exhaust bloke refused to touch it) without any cutting.
Today I just had the decat done and am pretty pleased. Noticeably pulls harder and comes on boost sooner.
Aaaaand the handbrake is cooler than the other side of the metaphorical pillow

IMHO .... and nothing more than that....

I saw one comment about not wanting toxic fumes etc etc being sucked in by driver / passenger BUT was perfectly ok with a EGR remap done.
*As already noted, regardless of exhaust set up, its not ment to be leaking so it fills the cabin.
*Your EGR delete (which is illegal)..... what sort of emissions do you think your pumping out the back? it aint smelling of roses.
*I mean really, get a grip, you could put 32" tyres and do a 2" lift and it would be illegal.

On a technical note....
*A Defender 2.2 I drove recently (that gets used for "offroad use only") had a cat delete, a remap and a big inter cooler.... its about as impressive as a 2.2 diesel can get with bolt ons, pulled hard and clean through its rev range and didnt feel like it ran out of puff.

I wonder if there should be an allowance for primary producers to legally remove cats & DPF's to mitigate the risk of starting bush/grassfires.
I would have thought an insurance company would be in favour of that.

I agrees with everything you said.
But it has nothing to do with my previous comment. We are talking about different things.

What is clear is decat will have an adverse effect on health of driver, passengers and other road users (and we all agreed

What is unclear is what the benefit of decat will be in terms of horsepower and torque.

And I can not make a informed decision knowing onky the risk but not the benefit quantitatively. I can not estimate the risk benefit ratio for decat.

The cost is not just money but also health cost. I paid money and my health for the remap and egr shut-off because I was shown the power gain quantitatively on a dyno chart and I decide the risk benefit is in favour of the remap

It also my humble opinion and nothing more.

Again this is just me thinking out load and flapping my gums, nothing more...

People's health and or the environmental cost of doing mods, lets face it is the unspoken white elephant in the room. I dont believe you can bring up health as a con in a pro vs con decision if you do a particular mod or not. If so you are saying well if I get a X% gain in power, economy or other mechanical benefit I'm happy to sacrifice people's health or the environment in the process. I do believe that's how VW think when doing a pro vs con on profit and peoples health lost out (personal opinion only, I have no proven fact VW are scumbags).

Put simply, if you are a care bear enough to consider peoples health and or the environment, we wouldnt:
*Do EGR blanking or deleting.
*Do remaps for performance gains.
*Do cat, DPF or muffler deletes.
*Drive a diesel in any form.

From where I sit its all irrelevant while we have mid 80s, 90s **** heap trucks belching out huge amounts of noxious fumes. Australia cant, unlike other supposedly "developed" countries palm off trucks that no longer meet emissions to third world countries, we are stuck with them.

Do you eat sugar?

Risk Benefit ratio? For a decat? Wow!!!

Your health was worth the EGR in a risk Benefit analysis?

Epic fail....

For the record, the emissions at the site I work on, of dust and dirt, sulphurs etc is more in a month than 50 years of Tdci exhaust!

Australian government is willing to pay $60k for one healthy life year. This is decided by pharmaceutical benefit advisory committee (PBAC

The harm from the decat (if enough data) can be converted into quality adjusted life year forgone (due to ling caner/bladder cancer/COPD)and then converted into monetary value. That's if you choose money as the comparison medium. In this case, say decat on average cause x healthy life year so the health cost for decat would be X *$60K

Then you estimate the money you willing to pay for the power gain from the decat. Say decat gives you 40 hours power and you are willing to pay $20k for 40 8ncremental horsepower on top of the BAS 170 tune.

And you compare these two number so you can make an informed decision instead of gutfeeling or whatever I don't give a ****....

Everybody thinks this way. Just like tombie you breathe in those fumes but you are compensates with money where the risk/benefit ratio of your job roughly match your self-evaluated, magic number

Well I am trained to think this way anway. There are known knowns and known unknowns. But there are also unknown unknowns.
I don't want to be recuited years later in a retrospective study of the health effect from Decat.

Like I said, we are talking about different things or the same thing where you sign minimal value to health effects while I act like a pussies.

Just for a laughter
