  • Very little drone at cruising on the hwy. To answer the gas the mpg question. 17mpg city, 27mpg hwy.

  • For everyday driving I am a lot happier with the Magnaflow. Plus I hated how the Bullett sounded at light accel at 2500 to 3200rpms.

  • @dopesoldat666 what about on the expressway? on cruise control at about 65 hha

  • @jock1454789 i have a 08 ss i get about 17mpg

  • what gas mileage u get?

  • Sounds great. I'm definitely getting the Magnaflow Cat Back exhaust for my Impala LTZ.

  • Do you think this or the Bullet sounds better? I think the Magnapack has a better tone, but the bullet sounds like there almost wasn't a muffler, it sounded so aggressive lol
