Can anyone help with a couple of unrelated questions.
1) Do the DiD Pajeros have catalytic converters? If so, will performance increase if it is removed? I read somewhere that a blocked cat.con. on a Triton is hampering it's performance.
2) Did the Blisterfender SWB come with a 3.0 V6 engine or only the 3.5 V6? Were they only manufacture in '99 and '00? I'm looking to buy a SWB 3.5, but get conflicting/confusing info from sellers.

Can only offer an attempt at question one. As far as I know Catalysers are only found on Petrol engines and not on diesel engines. In diesel engines they use a system called EGR(Exhaust Gas Recycling) to reburn some old gasses and reduce exhaust emmisions. By the way my 2001 3.2 Did LWB now has 215 000km on and I think it is still the original exhaust!!
Albeit with a dent here and there on the center box 
. I will bet you no petrol powered vehicle will be able to claim that! It does however raise the question if it has not been blocked somewhat over the years and thus put a bit of a hamper on performance?? Just did 1000km trip towing and can't say that it felt sluggish, but who knows?! When I owned both a new and old Pajero DiD the performance on the older one did not feel inferior so I think it is still good to go!
On question 2 of the SWB Blister I am not 100% sure and would rather leave that to one of experts to comment.

Both diesel and petrol use EGR and catalytic converters. There are differences though.
Diesel engine exhaust systems can outlast the vehicle. Not so with petrol vehicles.

Diesel engines
For compression-ignition (i.e., diesel) engines, the most commonly used catalytic converter is the diesel oxidation catalyst. This uses excess O2 (oxygen) in the exhaust gas stream to oxidize CO (carbon monoxide) to CO2 (carbon dioxide) and HC (hydrocarbons) to H2O (water) and CO2. These converters often reach 90% efficiency, virtually eliminating diesel odor and helping to reduce visible particulates (soot), however they are incapable of reducing NOx as chemical reactions always occur in the simplest possible way, and the existing O2 in the exhaust gas stream would react first.
To reduce NOx on a compression ignition engine, the chemical composition of the exhaust must first be changed. Two main techniques are used: selective catalytic reduction (SCR) and NOx (NOx) traps (or NOx Absorbers).
Diesel engine exhaust contains relatively high levels of particulate matter (soot), consisting in large part of elemental carbon. Catalytic converters cannot clean up elemental carbon, though they will remove up to 90% of the soluble organic fraction[citation needed], so particulates are cleaned up by a soot trap or diesel particulate filter (DPF). In the United States, all on-road heavy-duty vehicles powered by diesel and built after 1 January 2007 must be equipped with a catalytic converter and a diesel particulate filter.[6]
Instead of catalysis, a reagent such as ammonia pyrolyzed in situ from urea, is sometimes used to reduce the NOx into nitrogen.
Thanks guys. Firstly the Blisterfender did come with both 3L and 3.5. I'm looking at a 3.5 this weekend, my toy for Atlantis 'Friday arvie club' and the Namib desert next year.
I will ask Kosie Swanepoel about the cat converter on the DiD. I'm also keen to chip the car for better towing.
