man trust me you need them, i changed my own manifold and never again, colm dunndrifter tell ya it a cunt todo, If you go with manufactor turbo lines it be a bastarded to get on (line up the bango bolts), braided lines are more flexable so it matter drop in the turbo and mani bolt everyting up and then you braided lines,

ahhh depends what you want shine or not, but belive me the manifold will get bloody hot,
i just have exgust wrap on the EX TEMP Gauge

if you want any i have a roll there

if you want i done a write up on it ill pm it over to ya,
