Yes, i agree that taking it to a shop would be the best way to go. There are many major problems and setbacks you could run into, and unless u have a hoist and a fairly large selection of tools to use it will be a waste of time even trying. I put long tubes on my car and it didnt go to bad but the engine bay was clean and pretty low miles on the car. However with the help of a couple buddies, we started at 6 pm and never had to bother waking up the next morning for breakfast. There is even less room to work once the long tubes are in, i still have one bolt to put in and 2 to tighten up yet. So basicly determine if the risk is worth it and if its worth the time.
