Am I ready to install my headers?
Ok, from now on I got:
-Exhaust manifolds gaskets -Paul's dipstick bracket -OBX headers -Patience Haven't received the headers yet though, will I need to have them surfaced? I will also need to order a chip from Marc Haibeck. Do I need something else? Bolts? o2 harness extension? Permatex? Thanks! Last edited by MuRCieLaGo; 03-02-2016 at 05:19 PM. |

Re: Am I ready to install my headers?
My 94 did not need O2 sensor extension. I believe OBX headers, due to fake cats, O2 sensor bungs are 3-4 inches forward compared to Stainlessworks headers.
Any other OBX header users remember different? Also, I used Permatex high temp copper sealant per Phil's recommendation. Seems to help the seal and keep the bolts from vibrating loose. Although I used Stage 8 bolts with locking tabs, Phil's suggestion was not to use the locking tabs since header gasket tends to shrink at times necessitating re-torquing of header bolts - impossible once locking tabs are used. However, there are two bolts impossible to get to once dip stick bracket is installed. For those bolts I used the locking tabs knowing I won't be able to re-torque.

Re: Am I ready to install my headers?
My 90 needed O2 extension.
My stage 8 fasteners, the locking clips would not fit in the groove, so not locking. In my case they served no purpose making for some expensive header bolts. I also ended up shimming the engine at the motor mounts to clear the steering shaft, the ceramic coated headers rubbed the steering shaft. |

Re: Am I ready to install my headers?
I cannot answer that as I had purchased used Watson Headers and just bolted them on..
