If you do remove the second cats, don't forget that it takes time for the ECU to adapt to. The adaptation takes about 1-2 tanks of gas. There after you will feel some power gain in the mid to high rpm range. You do lose a little bit of low end torque.

- N51 Engine with AA Headers, AFE Stage 2 SI Intake, Custom 3" Exhaust merging right after the headers.
