Help!!!
My Boxster has an odd exhaust rattle. Only present at peak temp, as soon as it idles for 30 seconds and cools down the rattle quiets.
I've worked with my local shop to rule out all heat shields. Replaced the muffler and header cats.
I've read just about every exhaust rattle post and just can't figure it out.
About to give up after spending months, huge $$$ and getting nowhere...
Any suggestions welcome...
