    Try any exhaust specialist that offers stainless pipes.

    Alternatively, fit any exhaust system from the 1200 Mk1 or Mk2 that did not have the flap valve. They all have the same mounts and straight swap.

    yeah i've a piece of Stainless Pipe from a fellow Tosser on here, works a treat, removes the sticky Flap.

    try a search as it was two years ago, just a simple tube unlike your e-bay item.

    The flap valve is 63mm outside diameter and 67mm long with a wall thickness of 2mm. Go to a local metal supermarket and get some stainless pipe cut.

    I took mine apart today for no other reason than interest. It wasn't fully open but free to move. I took measurements and removed the 2 cables completely. I'm guessing that the servo box needs to stay or it'll throw up a fault code through non communication. I replaced it until I can get a stub pipe to remove it altogether.

    I've done some more reading and that seems to be the way ahead. I'll remove all of mine and see how I get on.

    Just fitted one from Nippy Normans this evening.
    Yes, seems a bit pricy for what it is, but can anyone really say that any of the after market exhausts that many of us fit are worth up to £5-600?
    The NN piece is fine and the edges nicely finished and was a perfect fit. It arrived in the post today and it's fitted. Good job.
    If you can be arsed taking the time to go to an exhaust supplier, explain what you want, faf about until they cut it and then travel home again to save a few quid, then go for it.
    I just removed the exhaust and flapper valve, along with the control unit. Removed the cables from the control unit and covered the holes where the cables were with pvc tape. Replaced the unit and plugged it in again so no fault codes show up.
    While I had it all off, I gave the clamps and pipe ends a good clean with emery paper and a rotary wire brush.
    Used a bit of copper grease when putting it together so it comes apart a bit easier next time.
    Looks a neat job and there's a nice bark out of the standard silencer now. Fronts have been de catted btw.
    Recommended mod for the TC even though the flappy valve on mine was still working.

    I got a few cut today and fitted mine removing everything else. I'll stick all the bits in a box and put it on a shelf in the garage in case I decide to reinstate it at some point in the future.
