Hi
I have a Nissan Almera 1.5 Hatchback 2006

The front exhaust (with underfloor cat)requires to be replaced
but Jonh Clark our local Nissan dealer said that their were
two types of front exhaust one with out the underfloor cat
and one with.
They then said that Nissan do not make the underfloor cat
exhausts any more
I asked if the front exhaust with out the cat would pass emissions,
but they did not know

Where can you buy a front exhaust with underfloor cat ?
or
will a front exhaust with out underfloor cat pass mot emissions test ?

Thanks Iain
