What did you do to your Cherokee today?

2 into one then 3 into one? I was looking at some early inline aircraft exhaust manifold systems awhile back made for turbos and always thought something like that might work also. They ran short outlets from the ports into the side of one larger tube configured kind of like a normal cast manifold to the turbo. But because the collection tube was significantly larger in diameter there was no resistance at all until it got to the turbo vanes. They had the short outlet pieces aimed so that they created a pre-swirl in the larger tube on it's way to the turbo. Always wondered if this might be something to play with.

Think the O2 sensors on the right side would get hot enough with only 3 cylinders going through it?

Ordered ball joints for the Cherokee so that whenever I finally get around to sleeves and c gussets I can put new ball joints in too instead of frying my old ones, and I got a piece of pipe welded in the Comanche to temporarily replace the muffler till I fix the backfiring. I just couldn't stand the noise level in the cab anymore.

From what I have seen here some of the newer ones with the inline 6 do have two piece headers and run two pipes into a single further back. Tell you what, I would be splitting these into duals!
Back in the day we used to take cast manifolds and cut and weld them into what we called "spit manifold" dual exhaust systems. I don't know if it was because of the firing order or what, but they really sounded GOOD! lol

Had a crack in the exhaust manifold that was in a spot that could not be welded. So I bought some JB Weld Extreme Heat. It says it will fix things like this. Sanded down the area of the crack then cleaned it with brake clean. Added one layer and let it cure for 6 hours then added another layer. Will report back tomorrow night if it worked. Fingers crossed.

My understanding was that this was only for the 00 and newer split manifolds but you can't bolt a split manifold to the older heads due to port size. I honestly would like to know how much work it would take to put a split header onto my 97. Even if not for running dual exhaust managing the exhaust manifold would be so much easier.

Quoting myself for context. I am happy to report that when I started my Jeep this morning the exhaust leak was gone. Drove about 50 miles today and the JB Weld Extreme Heat is still holding strong. I knew it could handle the heat because I have seen regular JB Weld survive inside the combustion chamber of a cylinder head for more than a year of driving.

Stopped by XJWonder's place and picked up a new set of HD Offroad rear stiffeners and a still in the bag RK Long Travel Stainless Steel front brake lines!
