Transverse Exhaust Box woes
Posted: Sun Dec 17, 2017 7:11 pm
Thanks to Dave, AKA Bigvalvehead, I now have a NOS early Elan+2 transverse Exhaust box.
Several people here including myself have experienced badly fitting Stainless Steel exhausts systems as supplied by the usually excellent main retailers. I think these are made but Double S but I could be wrong.
My woes began when I needed to remove the centre pipe and box and ended up cutting the original mild steel centre pipe in two or more pieces which I threw out before the new one from PM arrived.
Needless to say after much huffing and puffing, it eventually fitted but with the end result the exhaust pipe was more or less at 30 degrees to the ground.
Whilst I have blamed my limp exhaust on the SS centre pipe I think think the SS box is partly to blame. So far I have two and both were the same.
Now I have a the NOS item you can see significant differences.
Pic 1 shows the two boxes side by side. the NOS item is on the left.
Lying flat on the ground the NOS item "box" is almost horizontal and the pipe sits about 5mm / 1/4 inch above the ground, whereas the pipe of the SS item is lifting the box about 5mm / 1/4 inch off the ground. So in total there must be a total difference in alignment of about 10mm / 1/2 inch. See Pic 2.
With the box lying on the floor in the same position Pic 3 shows the brackets to be vertical on the NOS item,
Where pic 4 shows the SS items bracketry to be inclined.
Pick 5 is on the Pipe side with again the NOS item on the left clearly shows the that the box of the NOS item sits horizontally with the brackets vertical compared the the SS items.
So far the test assembly is looking good and the pipe horizonatal, once the new hanging straps arrive I will do a final fit and post he results.
I hope others find this useful.
Best to all and of course Happy Christmas and of course thanks to Dave.
