I am not sure if I should get single or dual catch can from SXTH.
I read this
Once you increase the boost you will start accumulating oil on the breather side as you will start getting blow by, due to the increase in pressure.
in this thread (post from [MENTION=321]robz32[/MENTION]).
I might do intake and cat back exhaust in future. Not planning to tune or do any other mods. Do I need dual?
If you are staying within the factory boost specs then you can get by with the PCV side only.
But if you are planning on adding a piggyback later on or an ECU tune, then dual is recommended.
