Any1 know where or have a part number for a dump valve for my octy vrs 08. 

I do not believe that there are dump valves for diesels. Whilst I've installed one years back for a friend on his diesel Fabia VRS, You couldn't hear it over the diesel itself, that and it spat oil over the engine over time. It was soon removed and binned.

 

The best you could do, is straight pipe exhaust, open cone filter, possibly decat/PDF delete.

 

Straight pipe. Decat. EGR delete. Open cone. S212 Hybrid turbo.

Thanks

God that sounds naff!
