Editing Replacing the exhaust heatshield with Nimbus (section)

==Replacement of the OE shield and some extra...==
What I've done is very simple:

* remove all exhaust components
* remove the old heatshield (in one piece!!)
* take the old heatshield and 'crush it' on the sheet of Nimbus. Draw a cutting line around the original cardboard. '''(take at least 2cm around the old stuff as you have to fold Nimbus round to stop it from falling apart)'''
**Do not cut it at the point where the manifold goes into the engine bay, you can simply fold that around the subframe and shield the area which isn't shielded at this moment.
**Do not cut the holes for the exhaust mounts! (I did that, but it's useless and would only introduce new 'leaks', so I covered it again)
* form the Nimbus so it'll fit in the car. Don't forget to shape some extra's (a cross or so) to prevent it from rattling)
* use long and wide pop rivets to fit the new heatshield.
**Drill hole, stick pop rivet in from above and push a large outside diameter washer over the other side of the pop rivet to spread the load. Preferably use more pop rivets then original to get the whole thing stable.
* Create a tunnel made from Cirrcus which fits over the manifold and cat. I've bend the side approx. 5cm down to catch the heat. (also here, you will have to fold the sides, so you need to cut a bigger sheet then the actual size needed!). Exactly same story here with the pop rivets.

I had a bit of a problem as the pop rivets initially were not long enough. This can simply be solved by tapping the area around the pop rivet (diameter of the washer)

For the manifold end on the engine, I formed a sheet around the manifold and attached that to the boot bulkhead with square pipes of ali.
