looks a whole bunch like mine , which is all 3 1/2'' .
Not sure a 3 1/2'' H pipe is worth the weight on a full 3 1/2'' system , in my case -------?

I did it to mine just for the sound, turbos don't need the cross over but I figure if it deepens the tone on a NA car why not, plus if need a be can always remove that rear portion and add dumps where they connect for race day.
