RS2 and S2 exhaust manifold differences

[Oak16v]

Hi guys im in the middle of doing a 2.0 16v Turbo conversion on my mk2 golf
I was after a S2 manifold but ive sourced a RS2 for a reasonable sum, i hav a S2 turbo and wastegate. just need intake maifold.
What is the main differences ?
What should i be looking out for in case of copies?
Any help on this will be much appreciated

Cheers Billy

its

better flowing and can do more hp, look for cracks etc, there is some thread on here about fake one (copy) search button is friendly

Yeah did a search thats why i noticed alot of copies around, so is there any difference between a S2 and RS2 item's

IIRC the s2 mani is 2 1/2" bore and the RS2 is 2 3/4" bore like urquattro-island said better flow so more bhp from the RS2 item.
