Well, the exhaust cracking has finally started on the near side at the front of the can. Only 2200 mikes on the clock. Well done MMC.
After careful consideration I’m fitting a flexible joint in front of the cans and passing on the MMC fix of a third can support as I don’t see what that has to do with the problem. Making the can more rigid with the front pipe being pushed around by the engine makes no sense to me. I remember an old friend telling me that if glider wings didn’t flex they’d snap off.
Just a word of caution. I helped a friend with trying to sort out his Brooklands exhausts when they started cracking. To cut a long story short, we re-welded the cracks, incorporated new gussets to strengthen where the pipes meet the box and fitted flexible sections just forward of the boxes. It didn't work and we spent a significant amount of money and time finding this out. Once they start cracking no amount of welding will sort them out - it just moves the point at which they crack. The solution was to take the car to an exhaust specialist and have them fabricate a new system similar to the original design but incorporating the gussets and additional flex joints. They were critical about the way the pipes had been joined to the boxes so also improved on these areas. The work was completed in one day, cost £600 (cash no questions asked) and so far seems to be holding up well. They sound good too!
