I believe the spins hang a little low. Lemme know if you go with them and enjoy them.
Spins are no larger than any other muffler with a 4" depth, so they won't hang any lower than any other muffler. They also make shallower ones, the ones I am getting, the 6000F is about 3.25" in depth. The issue isn't the muffler, its how low our cars sit and where the muffler hangers are.
I am putting a hanger right into the floor pan under the rear seats which will allow me to pull the mufflers up as close to the floor as I want. I may have to add a heat barrier onto the mufflers but I'll see how it goes. I think with the shallower muffler case, and additional hanger, I can get them to hang no further down than my subframe connectors are. I hate to go into the floor but it has holes there already from a previous owner. Seems to me that without the transverse muffler, there is too much weight hanging and the mufflers work their way down lower as time goes on.
