I have the Apex 3" Catback W/ N1 Muffler from apexmotersports. The problem is that they dont make a 3"downpipe for our cars. Is there anyone that makes a 3" downpipe that may fit to the Apex catback. Im willing to do a little fabrication.

Sounds like you just got your answer. Find a good shop and fabricate.

any downpipe made correctly will fit with the catback.
the diameter of the outlet on the s-pipe is 2 1/4, and slapping a 3" downpipe will probably not yeild better results than the 2 1/2".
get a custom one made from the turbo, that should yeild better results
 
if your replacing it from the turbo back 3" is great!
if not and just after the s-pipe........all im saying is a 3" will not yeild a big difference from a 2 1/2 if the outlet is just 2 1/4.
 
I would like to see a new turbo manifold that brings the turbo away from everything more. Just to get some more clearance. *sigh* never gonna happen for under 500 bucks..

I'm definitely not getting any warranty action for my P5.

Why not make a bracket that offsets the AC compressor a bit more?... So, the AC compressor gets moved toward the radiator and up a little higher.. That would give a little more room to do a less radical bend from the turbo and go under the car.
