Absolutely. We've been informed now that the installer on Mike's car in particular simply folded the vacuum line over on itself, and put a ziptie around it to clamp it. For the benefit of the forum and anyone installing any exhaust system (not just Eisenmann), be sure to create an air tight seal when plugging the vacuum lines leading to the rear mufflers. Anything less than an air tight seal will cause problems.

Mike, I am very glad that you and I got to speak today, and I hope to hear from you again soon!
