    Disadvantage to welding the system is that if you want to replace a muffler or glass pack or whatever you're running at some point in the future, you'll have to cut as opposed to un-clamping.

    Its amazing how there is much less hate on this forum. If Bill were preaching Spec .01 on that other forum he would be banned in an instant for showing pictures of his crankshaft pulley.

    Here are the pics of the headers I have. Can anyone identify? I believe the orientation is such that the outlet pipes face forward (car), but I don't know if they can go the other way around or not.

    When it comes to exhaust tubing sizing, is referred to by its OD or ID? I included a shot with a tape measure, what diameter flex tube would this call for? Notice too that the passenger side header has port for EGR? I'm going to have to put a piece of straight tubing inline somewhere so that I can get my 02 probe inserted via a bung. You carb guys don't have to worry about that.

    Thanks.

    Turn the tubing clockwise to tighten it.

    You may discover that guillotine clamps aren't even necessary afterwards.

    If it were me, I would grind off that unusual tapered portion and weld in a piece of straight pipe.

    I've got a set of those too. Came with my Peugeot sourced engine, so I've just been calling them Peugeot manifolds:

    They are designed to accept a flared exhaust end like this:

    Problem as you can see is their extremely small size. Certainly doesn't match any of my Ford fittings (2"). Probably wouldn't match anything from Jegs or Summit either. You might have success shopping European suppliers:

    Bill, I got the adapters at Summit Racing believe it or not. 2" so I'm making the whole thing 2". I've got the cats and the mufflers, hangers and the clamps. Got the old stuff out today for the most part... What a bear! On the drivers side 4 of the 6 studs came out, but 2 of them stayed in and the nuts came off. Secret to extracting studs? Passenger side manifold tomorrow. Will flare the muffler ends to accept cat pipes and probably weld them. Did you tap all of your virgin holes and go larger? DMH has the 7mm guys for $1.80 apiece iirc. Did you buy their gaskets or make your own?
    Thanks, looking forward to the new system.
