    My Dealer(Bentley St.Louis) has told me that you can take out & replace the manifolds on a F355 by removing the rear wheels. It looks to me the only way the manifolds can be changed is by having the engine out. I wonder if anyone here has had experiences relating to changing the manifolds.

    Josh, Wheels off inner fenders off remove muffler and cats then the exhaust manifolds fairly simplistic answer but its just straight forward and not a real problem. Hope that helps, Regards, Vern

    Access to them isn't all that easy from the side, but much better than pulling the engine. Just a lot of little stuff to move out of the way before the manifolds come out.

    Yea, I would never go to the trouble to pull/drop the motor for that. Actually the hardest part(if there is one) is manuevering the header around the engine cradle tubes and the engine and they are still there when you drop the engine/cradle unit out. I've removed/installed 3 sets and never had any trouble. Regards Vern

    The most that you would need to remove would be the oil sump tank on the right side of the car, (in addition to the rear wheels and the inner fenders). Absolutely would not take the motor out.

    You don't even have to do that(oil tank) at least I never had to.

    i have removed the fans and the oil line attached to the oil tank[actually only losen the bottom not and swong it out of the way . what header did you replace the oem with .the donuts can be reused but the thin band clamp on the stub pipe does not like to be over tighten . they are sold a with the flange and nipple . over $100 each side. i am trying some 2 1/8 clamps i modified . they seem to work but are labor intensive .

    I just replaced my manifolds. Here are some tricks to removing them:
    Remove the rear wheels, fender liners , Rear bumper, muffler assembly,
    cats, air boxes , shield below air boxes. Remove the CV boot heat shields . Double nut and remove the two exhaust mounting studs from each rear cylinder .
    I did driver's side first. I unplugged the spark plug wires from the coils , removed the wires from the retaining rings on the frame.Move them away from the manifolds.Remove the air injection tube assembly. I removed the radiator fan from the drivers side radiator.Remove the brake electrical tubing from the clip going down the verticle frame rail just in front of the rear wheel. Rotate the clip from a horizontal to a verticle position. The manifold should then come out. By a hair!
    On the passenger side, I removed the dry sump tank first . I had to remove the exhaust manifold from the cylinder head in order to remove the sump tank.
    I had to remove the cooling fan, the oil cooler radiator and its oil hoses first before removing the exhaust manifold.
    I installed the replacement manifolds in reverse order of removal. I even had to loosen the motor mounts (4) and tilt the rear of the motor up slightly to get the new maniflold on the drivers side to go in.
    Good Luck!
