Exactly what are the "slight modifications" needed on the JDM 4-1?

I see that on both the JDM 4-1 and DC JDM 4-1 there is a slight modification needed for it to bolt on at the collector end...exactly what do you have to do?

Just get a Carsound cat and you'll be just fine bolts with no problem and still pass emissions. There custom made for this swap.
