For Stage 2 Map - are we required to have straight down pipes? BM3 states their stage 2 map recommends them to reduce pumping losses. I won't be modding my car and you have previously recommended to me that stage 2 would be my best option. I have MPPSK but do not want to risk damage to vehicle in long term.
Can you please clarify if stage 2 is safe without the mods?
Thanks
