So i guess my question is, why has Tomei not released a catted version of their UEL header?
Also, does anyone know of a similar sounding header with a cat?

Their is little power gain in these cars with just bolt on bits.
Adding a catted header without a tune any gain will be very small.
Even a catless header without tunes gains are small.
Their are very few catted headers for these cars as gains are less and cost is generally higher due cost of cat.

I believe the fine is big for having No cats at all but if you leave the second cat in system, the one in front pipe you should avoid that problem.
Just be prepared to swap back the stock header for a test.
a good option in australia is the PSR header/ovepipe combo.

you going to need a tune or an o2 spacer to stop the P0420 CEL
