Go to your local Minecke and have them do it. Cost me $60 and 1/2 hour of thier time. The reason being, the rear hanger might need to be heated and bent a little bit. Plus they have a lift, tools, etc. to do it right. And if anything goes wrong, take it back and have them fix it. Bob
I did mine in my garage. It worked, but you have to be creative at cutting it to get it out without being over a pit. Love the sound though. Don't think it helped mileage at all. Might even be worse by one MPG or so (and I don't think that's due to operator trying to hear nice sounds!).
