Cost: 90 bucks
Dealer: local shop
Install: didnt come with instutions but it is east. take bolts off put new on.

Overall. ive had it for about 6 months and it works fine. It sounds really good. The power increase was really only felt on low end torque and high end Accleration. i get it 4 our of 5 stars.
