TT OEM Exhaust - Removing Both 200 & 400 Cell Cats
OK with my OEM exhaust I have the 400 Cell rear Cats drilled out and the front 200 Cell cats replaced with 100 Cell Race Cats. My question is with an OEM TT exhaust has anybody ever removed BOTH sets of Cats and run totally Cat free as externally nobody can tell

Yes you are right about gutting cats and leaving that empty chamber.

That would be a better option. Now you have to deal with the rear O2 sensor causing a fault code; although an ECU mod will fix it and I've read you can shim the rear sensor with some success.

Can anyone tell me what the cell count is of the stock cats? This thread says 200 cell for the primaries (ones closest to the turbo) and 400 for the secondaries but not sure that is correct.
Thanks!
EDIT: Found this thread that states there are two 300 cell cats which makes sense as I heard people saying the cats are 600 cell.
