I think you are much better off buying a scoop coupe 600LT than retrofitting. They come up for sale from time to time and the price difference isn't as much as the original option. I have one and it's great. I was sold enough to get a coupe instead of a spider. The sound it awesome when you want it to, under non-100% load it will cause a ruckus. Running in auto mode on the freeway will be quiet except when climbing a small incline which will cause the whine.
Splits exit behind both seats, don't obstruct rear view at all, direct intake to engine, totally awesome.
