I couldn't find a good video showcasing the difference between the magnaflow and the flowmaster super 44 3" exhaust. After making the wrong decision to go with magnaflow (wanted the few extra hp they claim) I went to the flowmaster.
Mods are:
Texas Speed 2" LT Headers to 3" off road x pipe
K&N intake
Had factory NPP (personally liked the sound of the NPP the best)
Now 3" axle back.
Made 409whp dyno tuned with factory NPP axle back.
