My 325i was so quiet, I couldn't tell if I was in 3rd or 5th in town. ( other than tach) 40 series sounds great, no raspy tin can like most imports. Good throaty growl and very little drone at highway speeds.

Put this one a 2002 Sierra 6.0. Had duals ran out. Sounds great. Good idle rumble. Good under load as well. Not super aggressive but loud enough to hear it. Slight drone with the music off.

This mufler is just what my husband wanted. Our old flowmaster just got old and time for a new one. This is just what he needed. It's the same as his original and sounds great. Definitely recommend!
