(AA)got muffler here in record time. All ratings(excellent) cause that is how it is. Installation real snap using friends muffler shop. Price a wee bit less than local. Quality "Flowmaster"(A+). My '04 Grand AM GT sounds "BAD TA THA BONE"! No offensive sound, but will definitely be heard as a low, mellow, rumble, parked, & talks to ya real good off the line. When up to speed ya got a low mellow, just right, sound which makes ya sit up just a little more in your seat and smile! YEAH BABY! CRUZ'IN!!!

Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.
