Sup guys had a question im not too familiar with the flat 4 set up in particular with the 2.2l outback sport motor.
pretty much i wanna make a custom exhuast for my OBS like i did on my 240sx.
on my 240 it is just a 3 inch pipe from the Cat on...
the 240sx has a 2.4l motor which for whatever reason loves the 3 inch piping even all stock (N/A)
I was thinking to do something similar with the OBS after the cat no muffler, kind of Trust DD style on it, but was wondering which size piping to use i was thinking 2.25 or 2.5 but what do NA subarus like?
Bad picture but this style pretty much like my 240 but dual (nice looking) tips
