pacesetter 70-1170 on 91 4.0 help

[mobile madness]

got these headers for my truck, hooked em up and bolted em down with stage 8 locking fasteners. all i need to do is fill the extra o2 sensor hole i dont need on the y-pipe and theres a very large threaded hole on one of the headers. is there any way i can determine what size those threaded holes are? i looked on their site,summit, and here and came up with nothing.

It's for the EGR tube. I used a metal putty to fill it. Hasnt cracked or leaked in 3 years.

thats wierd cuz these headers were supposed to be the ones without the egr hookup.

I asked my buddy at pacesetter for hole sizes and he sent me this...

O2 sensor fitting = 18mm x 1.5” thread

ERG fitting Driver side header = 22mm x 1.5” thread

You are correct. I decided to give em a call. Got oil drain plugs that size and plugged em off.

LOL. I'm fairly certain you are your own "buddy". But it's all good. Just become one of our vendors man!
