I had this on mine a few years ago. Crawling under the car, I could see it, but couldn't get to it, so luckily, decided to take it to a Bulgarian run place down the road, where I watched 2 guys struggle for an hour and a half to do it.
On the ramps, it wasn't so bad, but they ended up dropping the sub frame at the rear while leaving the front bolts slack and going in from the back, but I was very glad I didn't try it myself!
I think there was a recent thread on here where someone had changed there pipe by taking off the rear arch cover and going in from the side?

They have sold over 200, which kind of tells a tale!
