Exhaust question

I'm planning on euro headers and DKF section 1 pipes with 300 cell cats; the rest of the system remaining stock.
Trying to get a general idea of the expected change in the noise level. Does anyone know the size of the primary and secondary cats on the NA version.
Thanks in advance.

you can go fairly open flow in the cats and section one, and it will be fairly tame in volume and without drone, if you don't go messing with the crosspipe part and the mufflers.

What dimentions do you need on the secondary cats?

I was curious of the existing flow or cell count of the primaries (which will be gone) and the secondaries (which will be replaced with 300 cell DKF's.
I have a bit too much grey at the temples to be running around town confused as a street racer.
Also, the size or cell count of the euro cats which I believe to be more restrictive than the DKF 300's.
