imo its a watse of time using any other mani then the oem 2wd cast mani
inless your turbo is going to bigger then a t34 or t4, grpA cars run the 2wd item
im sure, stay well clear of stailess steel manifolds inless as stated a few posts
up they are round the 1000 quid mark which should be good qaulity id hope.......
i had a 400hp+ gts4 skyline an i got my hands on a s/s mani put it on, looked great
untill about 2 weeks later of good thrashings an getting it glowing red hot
it devloped fractures all over it, stainless work hardens when heated, .....s/s mani = shite imo.........
