Re: Exhaust Problem - What is `Front Cat. Manifold` - Cost = £1000.00 ???
I think you are getting confused by the different terminologies used for the exhaust system you are coming across
First of all and based on what you have described, your 2.0LT xtrail must be the face-lift model and if that is the case, you would only have TWO catalytic converters in your car, which is part of the manifold (also known as extractors) as seen in this pic below:
That fat part of the manifold is the 3-way catalytic converter and the wire sticking out is the O2 (Oxygen) sensor. This is the first cat. converter.
The second catalytic converter would be under the car and it's situated directly under the driver's seat as seen below if you are to look under the car:
The flexi pipe I was referring to connects between the first flange of the manifold to the rest of the exhaust system pipes as seen in this pic:
As you can see that first section is covered by a heat-shield, so if that is the part that has rusted and you can poke a finger through it, it's not a big problem and the heat shield can be replaced without touching the exhaust system.
ALL model xtrails have a ceramic core cat. converter and yes it is a potential threat and can disintegrate causing flakes of the ceramic core to get into your engine and damage the cylinder walls, but having said that, there are 2001 model xtrails on the road still with the factory ceramic cat. converter without any problems, so it's a hit and miss type of thing and depends if the car is driven under heavy load all the time.
I can assure you that there are NO x-trail is the US, so the forum you have come across might have been a Canadian based one.
HINT: Please try and cover one topic in your posts rather than talk about fuses and power sockets in a thread that is now dedicated to information about exhaust system, this makes your posts shorter and it will also be less confusing to future readers who might benefit from your questions and the answers given if they're to perform a search within the forum.
P.S. Please refer to the welcome note posted to you when you joined the forum and check out the forum guides on how to post photos and diagrams, so you can practice doing the same when needed.
