Added these to my car to my Borla catback system. I love the sound and could feel a difference right off the bat. They made the Borla system sound even better with no more sound added, but a nicer tone. After a retune the torque difference is great. They fit great, I did get some OEM gaskets though as the ones that come with them are pretty flimsy.
They look great under the hood, I would highly recommend them if you are thinking of adding headers to your car.
