Overall I am very pleased. Highly recommend these if you don't mind going catless on the 3.0i.

Good job on the install! I highly recommend flashing the eu2 tune (factory euro catless tune). The exhaust smell will go down 80-90%, no cel, and you'll see a little better mileage. Without the rear o2's, the x is running pig rich as the ecm is constantly testing catalytic efficiency.
