If you are thinking about getting them BEWARE. First the 2 demon bolts were to tough so I went to a muffler shop. Three hrs later with a torch and spray both loosened w/o busting. Then I had a seized oxygen sensor so add that crazy $200 to cost and half your day is shot and the final cost comes to $570. I am not happy with the very small sound improvement. Did not seem to be worth the bother.
