I just have a few questions arising from some scanning of the net recently. I would like to get a 2.5 inch exhaust upgrade, (would a 3" be more beneficial?) but there are some questions I need answering. My 90 will have to be DOE'd (Department of the Environment) like the MOT where they will do the usual checks and they will assess emissions, so I feel I need a catalytic convertor to cut down on my emissions. Do most of the custom exhausts ditch this element as it causes restrictions on gas expulsion?
Also does the turbo on the 90 1KZ TE need a bigger dump pipe? I have read about this on other forums for the surf/hilux as it seems a really good mod, if a bit difficult to achieve.
Is the main reason for a side exhaust so that there is less distance for the gases to travel through a restrictive pipe before they are expelled? In comparison to an exhaust travelling to the rear of the vehicle.
I would like a custom exhaust but I am wondering if I can make it practical, i.e will I achieve enough gain from what I put into the mod? I use my 90 for fishing trips, some light off roading and doing some towing/general pulling around the place. It spends 80% of its time on the road and I really just want to increase the engine performance for economical reasons and also because I love working on my 90. I will not be using it as a purpose built off road vehicle so want to keep her practical. Hope you guys can help. Liam.
