I believe the cat-back section works. My information (which is second hand) indiates the Z3 3.0i rear muffler is a drop-in on the ti, and has two inlets and outlets. It also uses the ti mounting locations. Plug-n-play. But it is heavy and quiet like the stock ti muffler. The 3.2 is fairly tame coming out of the cats alone so I was just going to run straight pipe. By the way, and luck on those motor mounts? |
