The back one is for npp exhaust and mine is still capped,, and and far as the front one I can't find my directions I had for the install or I would send you them and as far as my install i would just take a picture but I installed it so I still had the purge valve hooked up and not eliminated so that wouldn't help you either, but I do believe the one on the driver side ended up going to the bov and wastegates on the stock install if I remember rights and the u piece was eliminated. If I locate the instructions I'll pass them on to you, by the way how you liking the car now and did you get some updated hp numbers
