has anyone try fitting a whole 4dr gsr cat back on a eg hatch. Currently running a gsr motor with a custom cat with si hatch piping. The si piping is not mine so my friend needs it back so what do i have to do to make the 4dr gsr cat back exhaust fit. What do i do?

 

I may be wrong, but the s-pipe will fit, but not the axle back muffler portion.
