Hello Everyone! This is my first thread ever. I have an 2011 Ram 1500 ST Hemi. I put an dods14 muffler and replaced the resonator with custom tailpipie. Now I notice sometimes at the height of the RPM range as its shifting it let's out a loud shutter/rumble from the exhaust. It's a brief sound, but doesn't compliment the nice exhaust sound that's there throughout the RPM range. Does anyone know what that is or has the same thing going on with their RAM?
Thanks.
