One of the first things I did on my 2008 2.4 was to dump the cat!
It was MOTd a few weeks ago. When handed the pass certificate all they said was....that's a really nice Land Rover!  80" 80" 86" 88" 90"
Wanted, Forward Control Anything considered. |

guessing at 90% of mot stations it wont be a problem , most testers are more for safety concerns , brakes , rust etc
maybe a problem if you get stopped by vosa , they tend to go bit more mad about the rules would I decat probably no as I don't think the benefits are that much , and don't want any extra noise I know stainless welds best by tig even more so with marine stainless , but most standard exhaust stainless ( most exhaust stainless is cheap magnetic stainless with a high steel content ) will mig weld with normal steel wire ok , ok weld will rust , maybe not as strong but its a faster option for quick repair and still could last years |

One of the high three tuners (Alive, BAS, IRB) stock or have mentioned stocking in the future a sports cat for the puma. Yesterday u may want to put some emails in to figure out who. Could a second hand cat with the guts smashed out not be found ?

'Faux' ones are already available but look rubbish. This was a thread from Alive.....
http://www.defender2.net/forum/topic26709....sports+cat And a public forum unanswered thread question from a few months later. (May have had an answer by pm.) http://www.defender2.net/forum/topic30320....sports+cat If you go through life with your head in the sand....all people will see is an ar5e!!

I spoke with Alive this morning - the "sports cat" downpipe doesn't exist and will not exist since the price was going to be prohibitive. There are as far as I can tell no "faux cat" pipes avilable for the TDCi - they only way would be to make your own by drilling out the core of the cat.
(Speaking of the drilling out option, there was a thread on here with pictures from someone on the forum who'd done precisely this, but I can't find them. Can anyone else locate them? I'm probably being cack-handed!) It is rumoured that there was an "empty cat" pipe available from LR at some time for export markets, but I cannot find the part number and I doubt that it is readily available. Alive can supply a very smart decat pipe which allows the heatshield to be refitted. The outcome of the MOT would probably depend on the experience of the tester. There are several on here who have had this arrangement pass the MOT. I did wonder if a printed label with a convincing bar code and the words "catalytic converter" stuck on the middle silencer might be a low-cost solution! |

Afternoon Blackwolf.....
Oh the irony......it was my cat ZeDefender purchased and knocked the guts out of! Hence the reason I had to travel down the path I did when legislation changed. Mind you the freedom decatting gave the engine I would have been loathe to refit a standard one anyway. It was in my view the cheapest performance enhancement and engine protection modification you could do next to EGR blanking. Details here: http://www.defender2.net/forum/topic15424....p;start=45 I at one stage was contemplating buying a Ford Transit 2.4 one and adapting to fit by again fitting it where the TD5 one was, at less than £100 exc VAT it would have been a viable solution. a 'cat's a cat' and it is just a visible check. http://www.cats2u.co.uk/29666/Catalytic-Co...RANSIT/2.4 If you go through life with your head in the sand....all people will see is an ar5e!!

so this also happened to your puma too? Apart from my broken turbo i also observed a manifold leak behind the a/c compresor,but i didn't check the retaining bolts and nuts,thought that the manifold wrapped - as for the decat do it K9F's way. |

@K9F - Thanks for the link - I think I did find that thread but skipped the bit I was looking for!
@Fatman - Interesting to know it isn't just mine that does that trick with the front branch of the manifold. About once a year I have to tighten it up again. Curiously it is just that one branch, the others are fine. I don't have A/C on my Defender, and I am so tempted to machine a large chunk of that bracket that holds the alternator (and A/C compressor if fitted) to improve access and possibly cooling. |

Just because it's stainless doesn't mean you have to TIG weld it. Sure, TIG welding is the nicest sort but you can stick and MIG stainless (with appropriate stainless sticks/wire). I've never got round to learning how to TIG but have welded stainless stuff
However, an exhaust is quite thin which will make it trickier. |

I refitted my cat last year for the MOT, and can honestly say I've noticed no difference whatsoever in performance or fuel use 
And [As Munch says] with the cat It's a little less noisy [Mine has centre box removed], I actually prefer it now. No longer convinced by the 'Pros and cons' arguments ... My cat is staying put  Guns and Landrovers .... anything else is irrelevant. |

Well, "there's your problem" as they say on Mythbusters.
I thought there was little crack , I wasn't quite expecting this! This could be a bit challenging to repair, and getting the flange at the right angle won't be easy. Click image to enlarge Click image to enlarge |
