I've started working on my old eclipse again and decided to build a 3" downpipe. I would get the clearance I need if I could remove a fitting on the A/C compressor where the high side line meets the compressor. It looks like a service fitting of some sort that sticks out a bit. It would be great if I can just plug it. The A/C hasn't blown cold since 2000, so I'm not worried about recharging it if "by accident" I discharge the system.

why not pull the AC compressor, and lines out. it takes all of 30 mins, and will drop a good 15-20 lbs off the front of your car easily. i'm almost 80% sure you can still use the PS, with a different belt, if you remove the AC compressor.

My dad is insistent on keeping A/C. It's probably going to wind up as the family fun car.

I cut the flange to better accept my 3" pipe. My A/C is saved from my carnage.
