I got the below PM from Darryl and it's exactly what I did. I drove the front of my car on rhino ramps and was able to do the installation on those with plenty of room to work.
The steps are basic, but when you get under the car, you know what he's talking about.

Step 1: Remove Lower Engine Cover
Step 2: Loosen steering rack bolts (driver and pass. side). Then remove pass. side bolts completely
Step 3: Push steering rack forward (this will give you the space you need to work)
Step 4: Loosen Pass. Side Rack heatshield
Step 5: Mark both o2 sensors, then remove.
Step 6: Unbolt each downpipe at the 2-bolt flange
Step 7: Unbolt each downpipe at the bracket
Step 8: Unbolt each downpipe clamp connection to turbo
Step 9: Remove downpipes

Installing is the opposite of the above. Start with the shorter downpipe first. Install ALL connections loosely at first. After installing the first downpipe, you will need it loose enough to be able to maneuver the second downpipe in place. When everything is lined up with the corresponding bolts loosely attached, torque everything down.

Hope this helps.


Give youself plenty of time to do this.
