It`s a Corsa Sport Dual exist exhaust... with ZERO drone. Even towing 6500 lbs, no drone.
Highly recommend it
I had the American thunder flowmaster kit on my truck and it comes with the 30-series, so I swapped it out with the 40-series. Although it had a great sound, I lost low end torque and mileage and had loud drone especially towing. It also rusted out in less than 2-1/2 years. I was VERY dissapointed. This was on my 03 5.3. I swapped the magnaflow dual exist and gained it all back. Couldn`t have been happier.
The 6.0 is a different animal. I`ve read countless posts how bad they drone with different mufflers. Magnaflow SUV series works well on the 6.0 and I don`t believe nothing works better than Borla or Corsa as far as drone on the 6.0.
Just my experiance...
