Headers and E85

[Amaury]

Hello guys, recently bought the ARH long system for my 19GT and just found out, some headers tend to damage O2 sensors with E85 due to the placement and moisture. Noticed some headers have the O2 positioned in a 45angle+ but ARH doesn't do this. What should I get to manage the issue that doesn't involve relocating the 02 sensor position?

As long as you have a good E85 tune, you should not have an issue. My 2018 has been on E85 and running headers that the 02 sensors are not on a 45* for 2 years now, No issues. It's all in the tune...

I just did my stainless power headers and went on E85 today. Mine aren’t angled. But holy hell. It RIPS!!!!! Also threw some crusaders on the rear today too. But get em on n throw some corn at it. I can’t believe the difference.

Thanks. It will have a full dedicated E85R tune besides the 93 tune so most of the time the car will run 93. We only get race E85 down here.

Just have the O2 sensors re-angled so you don't stress about it. I did the same with my SW headers, and I feel much better. No O2 sensor issues.

Nahh, talked to my mechanic and he just said to leave it like that and if we have a problem down to road to just buy extenders since I dont want touch the headers.
