Installed easily. Not loud. Improved performance even in economy mode. Too early to tell if gas mileage improved.

got this for my 09 F150 4.6. The Multicore system was the only option available for my truck but I believe this was exactly what I was looking for. Def noticed better throttle response and power. I love the sound of this Borla! I jus wish they made headers for my 4.6 Id buy that too, oh well.
