identify this part ? A138s0253F

[grog]

i bought a second hand Larini exhaust system which came off a 400, and it also strangely can with a extra lotus 'Y' pipe/flexi. 

can't see any reference to the part number stamped on it. A138s0253F

anyone know this or what it could be?

sounds as if it may be  A132s0253F is off an Evora, type 138 is not on the drawing board yet....

ASM DOWNPIPE EXHAUST-3 INCH

thats what i thought, but it's clearly stamped A138,

plot thickens then. may be they just mis-stamped it.

A few months ago I ordered a new rear exhaust for my V6 MG and they sent the wrong one, although it was marked with the my correct part number by the manufacturer, it was clearly the wrong shape.

interesting, i had a look on deroure, and there a several, but not hundreds of parts with a138 prefix, they are mostly exige v6 and some 311.

@JAWS might know about this?

The part looks to have been marked up wrong by Janspeed. If anything it should be A132S0233F assuming it is a UK{ROW) part? A132S0253F is a Federal spec part.

If people are interested the part numbers are broken down like this. The first letter being the engineering level. Any changes to it mean it goes up a level. A to B to C etc.

The next 3 numbers refer to the model it was originally released on. 132 being Evora, 138 being Exige.

The 4th letter relates to where the part is located on the car. 'S' being an exhaust component.

The next 4 letters are randomly chosen unless it's a proprietary/"bought in part" which would use a 6000 series number, also the other rule is - LH/LHD should be an odd number, RH/RHD should be even (However, this rule was ignored a lot of times on the Tesla Roadster)

The last letter relates to its status, 'F' being a finished part, 'S' a service part and so on.

Thanks Jaws, this is super helpful, I've always wondered what the coding was for the part numbers
