I have sold my 2003 seicento sporting to my bloke and he needs a question answered.

Hi there,
There seems to be a change over at some point between 2002-2003 on the manifold and cat. I have a cat back sports exhaust but would like to change the manifold and cat to sports versions. But the 2002 model has the cat under the engine but my model(2003) has the cat in front of the engine and seems to be part of the manifold. Now the 2002 has the option of an aftermarket sports manifold and cat. Will these fit on my 2003 model or does anyone know a company who could help??
Many thanks guys
marc

What you need to do is to replace the later cat in manifold with the older type of manifold (an aftermarket one if you like) and a cat after the manifold (sports cat if you like). You may need to extend the wires to the existing lambdas and put a new boss on for the post cat lambda to prevent the ECU getting very confused.

Otherwise, no big issues.
