Few 99' B4 Questions

Relacing the clutch in the legacy at the moment,what the best gearbox oil to use?

Also Ive been offered a set of decat-downpipes and midsection(mid section rusting abit),would the boost be uncontrollable woth this setup or would I be better oft just doing the mid section?Thanks lads, baz

As standard it would overboost but the boost is controllable with a remap or boost controller.

Dunno what the best gearbox oil is

75/90.


and only cat in primary downpipe. other is in centre section.

it would make an already dangerous situation of melting a piston into a without a doubt one on 95fuel if drivin hard.

I am aware of this I dont really push the car on so Id say i'll leave it the car is running so well since I bought it apart from the obvious
