Yes, EC approved, not race.

Yes secondary CATs in place of OPF. This means 2 things for the UK:

1. I can remove primary CATs in future and still pass UK emissions test.

2. Secondary CATs will pass "visual check" that an OPF is still in place at annual test (MOT)

These CATs are 200 Cell hi flow cats with very little restriction compared to OPF.

They also will keep the noise down when I remove primary cats soon.

Remember before OPF the S55 had secondary CATs anyway..
