'00 Grand Am GT Flowmaster 80s (after)
Exhaust note of my GAGT 3.4L V6 after installing my Flowmaster 80s muffler this morning. Set up at this point is simply an axle back system. 2.5" single into the muffler, 2.5" dual out. I'm very impressed with the tone!

This is a couple of videos put together of my Grand Am with Flowmasters. I also have a Doctor Speed Cold Air Intake ( which whines like crazy but you can't really hear it in the video).
