Ok, here's my situation. When i swapped the TTA motor in the guy didn't give me a certain exhaust piece I needed. Basically its the piece that allows the pipe that comes off the cat(or test pipe ) to bolt onto the I-pipe. Basically I have to bolts holding the 2 together, its this adapter piece(or whatever you want go call it) TTA specific? Can I get this off of a GN? What's the actual name of the piece? HELP! lol
