i have searched already and cant not find anything concrete, i have a 92 LS400 i finally got my x-pipe in the mail and will be bending up a 2.25 in exhaust for it on thurs. The car had 2 bad cats last year, where i live in ca a smog test is not required after the initial registration, so I gutted the cats and re installed, now that im doing an exhaust my tubing will begin directly after the manifold. i will have the car off so i can measure on thurs but would rather order the part before i disassemble, my question is what is the outlet size on the exhaust manifold? is it 2.5 in? reason being i would love to use these reducers w/pre welded o2 bungs at this link

worst case scenario ill just fab my own up on thurs but this would save me a lot of time
