Hey frens,

Need to know which size of exhaust piping suitable for RB20Turbo? 3" or 2.5"?

2.75" to 3". ;) anything more than 3", you'll suffer a lot coz your low-end torque will almost be non-existence.

hey I thought Malaysia don't have 2.75" pipings, 'cause last time I want to change to this size and can't find ONE DAMN shop that sells it, only 2.5" and 3"!!!
