I will never put these headers on another vehicle I own, it is almost impossible to put on by yourself with out a lift and unbolting everything in the world around them, you will cook your starter rather quickly, your O2 sensors are so far back away from the headers you can't get a proper O2 reading so constantly running lean or rich unless you have a tweecer or some one tune it some way to compensate for the right pulse so give you right AFR. Only reason i give them a 2 is for the sound they sounded great
