I did this to the SD as well.

However, one point of note is the inability for the shop to put a center mount in place of the resonators. They tried twice. Each time, the noise from the exhaust would resonate through the cabin. I didn't insist that they hang the system with rubber donuts.........and, in retrospect........that probably would have worked.

So, it's mounted at the downpipe and the at the rear muffler, without any other support. It's very quiet.........but, the durability of the mounting system is definitely a concern.
