    There are several manifolds for the V8 Rover engine but if its definitely SD1 then ebay item number 301483530221 may help. There are some others for the MGB which fit closer to the block - are you haveing a complete new system?

    The remaining piping was made from six 900 bends (Clamco SSB3890 38mm 90 Degree Stainless Mandrel Bends) 10.25 each - three for each side. These were cut to length and then fastened together using strips of mild steel and a jubilee clip on each side of each joint, this enabled me to remove the three pieces of pipe as a whole keeping them in the correct orientation. The joints were then TIG welded (tacked) at three points to avoid distortions, the clips were then removed and a run of weld ran around the whole pipe finished the job.

    Try looking at http://www.clampcouk.co.uk/exhaust-r...rel-bends.html for various types of bends.

    Hi Michael. I am still looking for something to replace the failing O/E Marlin manifolds on my Hunter. Any chance you can post some more photos of the above fitted to your car, especially on the driver's side? I believe the engine mountings will be the same as my 3.9i V8 but obviously the steering column and chassis clearance will probably be more of an issue for me. Also details of your supplier would be appreciated. Peter.

    By the way I am assuming that the manifold ports & studs are the same on both the 3.5 and 3.9i engines? Can anyone confirm this? PL.

    Peter your right the down-pipe does come close to the engine mounts on both sides so I altered the mount to accommodate it. It also fouls the right hand side drain tap which had to be plugged.
    I will take some pictures ASAP but I am in the middle of a gearbox change which requires all the exhaust system to be removed which I have just done today !! but the manifolds are still attached so it should be very clear how much room there is.
    I'm not sure if the 3.5 is the same as the 3.9 but I had originally had a pair of P6 cast iron manifolds but they ended up cracking and literally falling apart so I'm assuming that most of the rover V8 variants are the same

    Many thanks Michael. When you take the photos can you please include a ruler in the pics especially if you can take a "front" and "top" view as I need to see the clearance for the steering and the chassis. I have an MOT 6th Feb so hope to get it sorted by then . Peter.

    Peter here are a few pictures taken today before you asked for a ruler (good idea) to be included

    let me know if you need any with a rule, you can get an idea as the manifold tube is 44mm dia

    Hi Michael.
    Many thanks for the quick response.

    Unfortunately my engine mounts are under the centre so it looks as though it will foul the down pipe.

    Photo of my O/Side one attaced:

    HUNTER OS Manifold L.jpg

    I have seen other tubular manifolds by Rimmers and one on the Locost forum but they also will either foul the engine mount, the steering column or the chassis at the front.

    Back to the drawing board I guess.

    Peter.
