On a mk2 vRS TFSI going stage 2+.........are they worth it? Will I notice anything compared to keeping my stock pipework?

Thanks for any help.

did mine on a TSI using an AUD200 ebay kit.  Definately more x-section especially at the turbo outlet.  My boost comes on a fraction earlier now but I did a couple of other minor mods at the same time so maybe it wasn't the pipes?? 

There's an improvement but money is better spent else where IMO
