Wanting to get rid of my exhaust leaks both sides at the converters what other years will bolt up to them and have the oxygen sensor hole don't need the complete assembly to the resonator planning on putting on a new y pipe to finish out the exhaust I've done both flanges are completely shot.

 

1993-1994 for sure

1990-1992 have some differences but I don't know if they will cause any problems

1990 uses different front exhaust hangar brackets (modified to be a single bracket for both sides in 1991 to reduce vibration)

 

After 94 did the mount style change?

 

1995+ exhausts are different. I am not aware of anyone trying to use those on a ucf10, even though they're similar

 

As long as the part in red bolts up I can route the rest of it hard to find any ls400 in my area right now
