Thread: 2.2 TDCi (Puma) CAT Delete

I was meaning the new piece of pipe with that flat flange on it guys.

Had to drive back from Evans Heads this arvo, outside temp was around 29-31deg's. stick with me.

I have had that big exhaust can under my seat replaced with a full flow sport job. I have also had the rear can replaced with a smaller full flow sports job.

So I had my electronic temp gun with me, the temp in the passengers footwell was 37.2deg's drivers side was 47.8deg's. So by removing the Cat can & wrapping the new pipe with heat tape will this reduce the heat under my feet?

If removing the Cat will reduce the heat I'm going to do it yesterday.

Cheers
Dave

Removing both the cat and center muffler lowers the cabin heat substantially. Pat

What would be the effect of just removing the cat from the can and rewelding it closed?

Lots of work (and it’s huge) and a big, non-linear (unless you weld in a pipe) box messing up flow.

Trying to be stealth will be a waste of time..just fit the heat shield back on the top and you’ll be fine.

Anyone in Melb with a decat, I would like to experience it before I remove it.
My 2.2 runs out of warranty in August.

btw. Removed the centre muffler last week. Can confirm there is no noise difference, but cant detect any performance advantages either.
I have a BAS remap city tune 140 bhp.

You won’t see a gain - that Cat is holding it all up

The biggest downside to remove the CAT will be no more heated floor in the winter

I think I might actually miss this....

Will removing the cat help the engine run cooler as my air con cuts in and out when working hard on a long run.
