These are the pipes I had a local shop fabricate, the pre 02 and post heat sensor should have a place to connect to, this is what is done on the aftermarket deletes as well.I believe i have fabspeed cats and the thermocouples are still indtalled as shown in this pic - do your bypass pipes have a place for the sensors?
I have cat delete pipes & high flow cats by Fabspeed, Larini, Tubi, etc. and all of them come with ports for the thermocouples. If you still need call/text 717-319-2100So to those who have put aftermarket exhausts on your G, what do you do with the thermocouples that were in the cats and also the cold junction box??
