Haha I've heard it is a lot better than the regular version. I first saw mention of it on this site for the dreaded wagon drone around the rear diff area. One guy installed one close to there and it really helped. Though when I looked on my own car, I didn't think there was enough straight section there for a 10" long resonator. Definitely is room on the midpipe (I used to have a cutout there), but not towards the end where it curves.
I may swing by a muffler shop and see if they think it can be done since I'm no expert at fabbing up exhaust pieces.
