I will be sending my FAIC exhaust to be recoated and while it's stripped I am going to have them weld the bungs for o2 sensors. I am not running a fuel management system that requires this, but I want to have that option if I ever change without the risk of damaging the ceramic coating. I would appreciate it if someone would post a picture or explain to me where locate these so that I can advise the factory. Thanks.
