well I installed it today, it took longer then i thought because one of the stupid bolts that connect the stock h pipe to the exaust manifold wouldnt come off, even with the impact gun, so i finally got some stuff to spray on it and it loosend up. Then I had a problem with getting the nuts on the bolts, but i got that settled, i am very happy with the sound and all, and for some reason, im not getting a check engine light yet
