Turbo exhaust questions!

[Cvanatta87]

Hello i have a 2009 370z nismo and i have a twin turbo kit on it and im missing 2 bolts that are part of the turbo exhaust and i can't for the life of me figure out what type of kit i have to try and get thr correct bolts any help we be greatly appreciated, i bout the car with this kit and the owner before me didnt know anything it has garrett turbos but i cant seem to find a garrett kit so im thinking thr piping is different, i had a guy tell me 1 time that its a older kit i do no it was installed in 2010 but he mentioned he recognized the kit because the windshield wiper fluid container wasnt bolted down to anything and was just sitting in there theres a smaller exhaust pipe C shape that wraps around the main pipe on the drivers side and theres 4 bolts and they so hard to get to it seems to be threaded bolts but the ones a alrdy took off dont fit im new to forum trying to post a pic soon

Im starting to think its part of the exhaust system because all the kits i look at don't have the pipe im talking about, my mufflers have no labels hopefully someone noes from the windshield wiper fluid container not being bolted in
