    So I did a gasket refresh and I'm having a hell of a time getting both nuts to tighten as a wrench is too big to get down there, now the far right one I'll just pick up a long extension to get to but how am I suppose to tighten the one on the left cause it's a super awkward position.

    I usually get the nuts snug and slowly tighten one then another. I can get a full socket on mine. I'm using the stock 02 housing with an aftermarket down pipe.

    If possible jack up front end and use a long extension from underneath, I was able to get a socket onto both. But like mentioned I also had stock o2 housing aftermarket DP.

    I can confirm with the others, on a stock mani/downpipe the nuts are easily accessed with a deep socket 19mm and an extension. Slightly jacking the front end by the subframe also helps if your car is too low.

    I too, do these from underneath with the front up in the air for room.

    Late update guys but I was able to get a buddies hand, raised the car up, had him put a wrench on the top nut, I then took a ratchet to the bottom and got it super tight. Worked just fine.
