Not to LWB, IIRC. But nothing an exhaust shop couldn't fix.
BTW, it is not much more difficult to use a GEMS or Bosch Y-pipe. Plug the after-cat bungs, and weld in a narrower before-cat bungs for 14CUX O2 sensors.
Anything is better what I have now. PO made complete exhaust, one solid piece, from manifold to tail pipe and took the y down to a single cat right below the trans pan, so i can't drop it, have to remove the whole assembly. Just want a simple bolt up oem style without too much fuss.
