We've found that not running heat shields will result in premature wear of the CV boots, and will cause CV failure in some situations involving especially hard driving. We install heat shields on all Eisenmann connecting pipes for that reason.
Hmmm, I might have a muffler shop do that for me on my Dinan system. Thanks!
