First of all searching on rattle on lotus talk garentees many hours of reading

. I did a bunch of searching and reading but still cant isolate my problem.
It started recently after my first track day where I took it pretty easy. Every time I take off from a stop I get a terrible metalic rattle. It is hot just a minor anoyance it is very loud. It sounds like it could be heat sheilding hitting on something but I checked it everywhere and couldent locate a problem. I have the stage 2 equast and I did notice the Brackets are cracked at the weld which is very common apparently. However I dont think that is the problem as the tips still feel very secure and I dont think they could move enogh to hit the diffuser. Again the sound only occurs when pulling away from a stop and is quite loud. It is coming from the rear and sounds more from the passenger side than central.
Sorry for another "rattle" thread and all coments are appreciated,
