Is this all in my head?
I recently removed my second cat. And to me it seems like I got some gains. Is this all in my head?

Best way to tell would be a dyno or 1/4 mile before and after.
It is probably in your head though, as the major gains will be seen with DP. |

Technically, any removal of exhaust restrictions should give you a bump in power on a turbo vehicle.

youre freeing up air flow and back pressure, you should gain a little bit sure. lol to 1/4 mile to test if you gained 15bhp of power. lolol.
