Thread: 2.2 TDCi (Puma) CAT Delete

And that's why I choose the remap plus egr closure and still sceptical about the decat

I think my willingness to decat is around 15 horsepower and 5 degrees cooler in the engine bay and less than $200

The driver and passenger should never get the fumes...
The exhaust needs to exit behind all openings and beyond the body work.

So apart from the mornings where it smells a little more for about 30 seconds on start up there shouldn’t be anything noticeable in day to day running.

We certainly can not notice it.

What I can notice - the floor doesn’t try to cook us anymore, the cab is more comfortable in warm weather...

And ask anyone who has driven ‘Ike’ - goes like a scalded cat with a firecracker up it’s arse...

Oh yeah - and the Decat, new pipe and box, and exhaust tip alteration (to stop melting mud flaps on a 90) was $400 even..

Thanks Tombie

So you do feel power gain from the decat.

The heated floor....Yes it is very annoying now but it will be a lovely "feature" in the winter....Positive thinking hehe

Regarding the fumes, I guess it is not a problem if the car is moving. but when stationary and during initial startup, you do breathe in a bit unconsciously.
And that's the main reason truck drivers has a high rate of lung cancer and bladder cancer and same goes for miners, heavy equipment operators etc....

If anyone with a puma defender can produce a dyno showing quantitatively the power gain...That would be great

So cut this little bracket and the cat is free at last....

All you guys that have removed their cats would one have one complete that I can get hold of?

I have a local race car exhaust builder that is happy to do the job for me but as I want it ceramic coated. Mine needs to be removed complete, new pipe work done, old setup re installed while the new one is sent away to be coated. One week later remove old & fit new pipework. If I got hold of the factory cat & pipe work he could build to match. This would save me loads of coin & time.

Sorry. Have to cut to remove.
