Noticeable Horsepower and low end torque increase, nice aggressive sound. Fuel economy horrible when pedal is put to the floor.

Overall these are very good headers for the money. They came with an instruction sheet and all hardware necessary for installation. If you get the black finish on the headers it WILL burn off, however knowing this ahead of time allowed me to prepare for it by buying high temp grill/furnace paint to re-coat them after driving them a few days. Two things I would mention, the kit does not come with any lock washers for the header bolts. Second, be prepared for the black paint to burn off and decide ahead of time to either let it go or pull them off and paint them. I've had mine almost 2 weeks now and they look great. They sound great and have no leaks. Overall a very good buy for the money.

If it wont kill you to dish out the money i would recommend these headers. I gained a consistent 2 mpg better, accelleration seemed to be smoothed out, definatly winds through the rpms quicker now, didnt lug at lower rpms like it used too. Didnt make exhaust very much louder at all that i noticed as i already had a custom cat back exhaust...just changed the exhaust note, a little more aggressive...seems that you can hear individual cylinders firing....i feel more low end torque for sure......I LOVE THESE HEADERS!!
