In-frame headers, problem with fit! Updated

I finally got around to installing my exhaust kit thats been sitting in the basement for 5 months. I got the passenger side header on just fine, real tight between starter and frame, but it fits. The drivers side header has a problem. It doesnt fit around the clutch hose and the brake distribution block is in the way. I can move the dist. block off the inside of the frame, but where is the best place to move it to? Or does it really matter?

You could move the distribution block up to the top of the frame! Or if you don't mind cutting and adding lines you can move it back. Good Luck

Re: In-frame headers, problem with fit!

[img]/wwwthreads_images/icons/tongue.gif[/img] First, I'm not really sure WHY a person would opt for exhaust headers on a Jeep.[img]/wwwthreads_images/icons/crazy.gif[/img] We used to "put up" with all the problems that headers are when we had fast cars which would actually BENEFIT from the scavenging effect that well-designed headers give above five thousand RPM. Other than that sort of application, they are trouble, trouble, trouble. That having been said, we'll address the problem that you are having.[img]/wwwthreads_images/icons/crazy.gif[/img] First of all,.....if you haven't wrapped specific areas of the exhaust runners with thermal wrap, DO IT NOW. Those areas should include anything that is close to electrical, fuel, brake fluid, clutch fluid, electric starter motors, and coolant. SECOND......DO MOVE that brake porportioning valve to another location. They even "FLOAT" them on some vehicles, letting the tubing support the block in mid air. THIRD.....double wrap the clutch hose and wrap any exhaust runners nearby. The clutch tubing can go just about anywhere a long as it is a steady slope to the slave cylinder. FOURTH.....put some 3" caps on the collectors and pipe them just past the body behind each front wheel. When you are wheeling, just open the caps and that way the sound of the exhaust will drown out the protests of the eco-nazis as they try to tell the liberal press what a bad person you are for going off the pavement with your Jeep.[img]/wwwthreads_images/icons/crazy.gif[/img]

Re: In-frame headers, problem with fit!

I am going to wrap the headers near those vital parts, I just want to get them in first so I know exactly where to wrap. The reason for the headers is because when I bought the jeep it had fenderwell headers on it. I didnt like them and destroyed them on rocks. The in-frame headers were half the price of new manifolds, so thats the way I went.

Re: In-frame headers, problem with fit!

MOST headers will give you all kinds of little hassles,
I'm running a set of Summit's $69 headers, buy a cheap header expect a cheap header...outside of having to dent 4 the runners to clear the spark plugs and the pass side mis-aligned and sitting to close to the starter for what I paid they work quite well, add some BBQ grill black spray paint and they last OK, when I re-do the exhaust again I'll be going back to manifolds...

and header thermal wrap isn't cheap ~70.

Re: In-frame headers, problem with fit!

After working all afternoon, I managed to get the entire drivers side exhaust on. I had to rotate the clutch cylinder to clear the header, grind a bunch of the flange to clear the clutch fork. Eventually, after a lot of bloodshed on the knuckles, cussing and prying I got it all to fit. Have to wait to attack the pass side till wednesday or so. Then I still have to wrap everything to keep the heat away from the starter, brake lines and clutch.

Coleman racing sells Header wrap, 50' for $48. Pretty damn good price.
