I'm about to put on my pace setter header on my 89 xj. When I was under her the other day and was looking at the exhaust manifold I saw the o2 sensor and then there was something going from the intake to the manifold could this be something to do with emissions and can I just do away with it plug it off or something and everything still work?? Its basically stock except for some upgrades but nothing to do with the intake and what would he a good gasket to get for m header. Do the header wraps work thanks for all who looks and replies

you got a link on the header you bought? i cant find an aftermarket header for my 90 renix...sorry to be off topic.

I'm not the most internet savy but u can google pacesetter headers and find all the info about them I have seen some on ebay also I mostly go to 4x4 forums and look through there parts for sale I got mine barely used off tennessee offroad for 135 shipped with the downpipe and it has the jet hott coating .......hope this helps

its not necessary. i removed it on mine without issue. it had something to do with cold starts or whatever it was. somethinhg that was fixed by something else. I know it doesnt sound like much help here, but yeah, go ahead and take all of it off and youll be fine.

do you mean the egr going in just under the TB, or the big tube that goes to the airbox?

That tube goes to your intake to warm it up faster. The hot air from the exhaust warms the metal in the intake or some **** like that. You dont need it but it does help.

Yeah Its the egr thing my header didn't come with the hole in it for it so I guess ill just plug it off somehow and be done with it its an off road only xj so its not a big deal just wanted to make sure before I went REDNECK INOVATING lol............... anyone using a header ever used header wrap???????

Lol that thing is essentially useless, i cut it off my airbox and it actually runs better.

So my downpipe slides over the bottom of my header were the collector would be so should I clamp it or weld it or is it ok just slid onto the header this is the first time I've ever seen this type of set up
