My car is 2018 Gtr premium
Is upgrading injectors a "requirement" if I'm just doing:
3 inch Catless Downpipes and 4 inch full straight pipe? (no resonator/ no mufflers)
I have no plans of doing any modifications in the future other than full straight pipe exhaust.
Cause my local shop is telling me that it is perfectly ok not to upgrade injectors since its just exhaust,
there are also many members in my local Gtr club who have changed to catless downpipes WITHOUT upgrading injectors also (no check engine using armytrix CEL terminator ), the only difference is that, they are running Armytrix full exhaust with mufflers and valves, while for me I have planned to use 3'' Armytrix Catless downpipe and 4 inch full straight pipe.
They have doing this for a long time, but I've read some sources that downpipes will max out stock injectors so I'm confused.
However, I also dont want to change parts unless they are required cause i want to keep my car stock besides exhaust
as of now, my car is all stock, no tune whatsoever, turbo boost is also all stock.
I dont join races, but do occasional WOT to redline. Temperature in my area ranges from 85-95F
Thanks in advance
Hope someone can help me decide.
