It actually has a lip on the cat to header to seal it properly. Fitment was perfect though. CEL was the only problem which was easily resolved with the extenders.
Yes either get the Stillen or Berk and do the non fouler(L extenders) mod to fool the o2 sensors or just get the Fast Intentions HFC that already has "L" shaped extender that will NOT trigger the CEL.
