Need some opinions on exhaust
Hello friends figured this would be the best place for this,my question is would there be any benefit in going to an aftermarket catback power gains wise.
My thought process on why it may be beneficial is i have my ewg routed back into my downpipe,and the catback is an sti spt performance catback which is about 2.5 piping I believe,currently hitting a peak of 32 psi on my gen 2 3076,so maybe less back pressure with that high of boost and a recirculating ewg may be quite beneficial but I'm not sure Only other thing of note that I can think of that would be worth mentioning is my downpipe is catless.i look forward to hearing your opinions thank you!

You should definitely go 3" especially with an upgraded turbo This is also an option
