The cat to muffler connection alignment is not AAA.... it may take some copper silicon to stop the annoying leaks.
The only other concern is driver's left, one header tube hangs pretty low and might be a clearance issue... especially is you ever want to lower your car!!!
I would show you a picture, but I can't seem to upload one.....

per Porsche tech.manual:
- Exh. manifold (M8X28) = 17 ft.lbs.
- bracket for muffler holder (M8X40) = 17ft.lbs.
- cat. conv. clamp = 13 ft.lbs.
- clamping sleeve NSD torque = 34 ft.lbs.
- tailpipe = 17 ft.lbs.
This should cover your entire exh. system.
Have fun.
