I've got a JDM 96 ITR header. Its definately fatter and internal diameter of the piping is bigger than the AUDM headers. Problem is because of the bigger diameter, the donut end flange wont line up to the AUDM cat.
Thing is...people sell JDM cats to fit AUDM headers. Does that mean that the JDM ITR cats are different to other JDM cats?
In any case...i'm using a b16a header atm just to drive it around, but do you think i should just take the cat to an exhaust shop to weld on a bigger flange or is there some other way short of finding a full JDM exhaust system?
