Ever since I had the Flowmaster 10 series installed there was a distinct rattle that progressively gotten worse every time I drove the car. Today I jacked up the rear to investigate. The left side muffler tip was the culprit. I think the muffler place forgot to tighten it back down after the installation. The right side was on tight as I checked it. Once everything was tightened the rattle went away. Nice when it’s an easy fix.
I also checked the air and set the pressure level to all four tires manufacturer specifications of 44 psi.
