this thing is awsome. it sounds sick, there are not check engine lights and i installed it in my 04 saab 93 2.0t. Suprisingly a pretty easy instal. the hardest part of the instal was tightening the lowest bolt on the heat shield and that wasnt that hard. i love the sound of it and makes a difference in acc and sound. awsome product. i would recomend it for any type of driver.
