Exhaust Codes

[CraigHew]

Just noticed a plate on the inward facing part of my S2000's exhause pipe (the one between the manifold and the silencer) which is stamped up.

 

Any ideas what the codes mean?

 

 

Just curious really

Was  it manufactured July 13th 1949? ​

[Mark (smokey mow)]

The top number is westfields part number

[Andy (Sycho)]

I take it that's a new decat pipe.

[CraigHew]

It is a decat but was fitted to the car when I bought it.  I subsequently bought a cat pipe from the factory which has 1711061  48005  7/13/30  codes.

No. July 13th 2049.

[Nick Mace]

It's a best before date.  Whatever you do, don't eat it after July 13th 2049...

[Andy (Sycho)]

Mine have the same numbers bar the date part the cat says 7/14/21 & the decat 7/8/15 which was about when I brought it.
