I know its not really for this forum buut...

I have for sale an mongoose 3" backbox for an 07 impreza,
2x cats, one standard one high flow

after... £50 for the back box and £20 each cat.

any info on the cats?
if for any reason there's no interest and you consider selling seperate parts (though you have listed the parts with seperate prices...) might be interested in a cat, depending on shape, cell count, inlet/outlet size etc

the cats are 2.5", cant remember the cell count off the top of my head, but one came off the car when the prodrive pack was put on, the other is the one from the prodrive pack when the mongoose pipe went on... ill try find out the cell count for you

awesome! 2.5" is what i'm after, any photos? that MAY be more important than cell count atm.
i'd need the inlet and outlet as straight and inline as possible, cell count, well if they're from a prodrive pack, i'm sure they'll be ok
