Elise S2 111s VVC - Catalytic Converter

[stephen7]

Hello

I'm in need of a new Catalytic Converter for my 2004 S2 111s VVC elise, engine code 18K4K

The car is currently fitted with factory supplied exhaust and Cat

There seems to a abundance of them available on Ebay, however they all seem to be for the18K4F engine, rather than the 18K4k (VVC version)

Will the 8K4F version be suitable for the 18K4K engine ?

Does anyone and suggestions where a 18K4K version can be obtained

 

Thank you
