Technical HGT CF3 catalysts

[DaveMcT]

My 2001 HGT Punto has a short exhaust manifold and two catalysts at the front of the engine. It also has the usual larger cat under the main body.

Does anyone know if a free flowing manifold can be fitted as I'm sure the front cats strangle the engine at higher revs. More importantly, will it mess up the MOT?
I dont plan to take out the main cat.

PS sorry if this has posted twice - my original post seems to have vanished.

Supersprint manifold gets rid of the pre-cat's and it will still pass an MOT.

Just checked them and £s = Ouch!. Nice kit, but unless one turns up on fleabay it will have to wait.

Cheap upgrade (well free infact ), its not the same as a sillysprint manifold but not that far off. Smash the precats out of the downpipe, the engine will rev a lot more freely,

Just make sure you remove the Lambda sensors first,
