mileage i have no clue what i get any more. but i do think there was some power increase mainly cause i got rid of that crap y pipe design.i can still spin my big old tires if i want. im also planning on headers too.
I have Berks B-pipes with High flow cats. and the O2 sensors are mounted after the secondary cats. they are mounted on O2 Sensor extenders
which allows O2 to work properly without getting ECU Codes.
This way you can gut the primary cats and even install aftermarket headers.
Berk Performance. 304 Stainless steal there is 1 for 2wd and another set for 4wd
the O2 sensor locations are in different locations because of the transfer case.
There is 1 more company I cant remember the name now.
These are made for Titan and Armada everything fits on pathfinder except the passenger rear flange. it needs to be rotated. what I did was cut and weld oem pipe between the muffler and the rear of b pipe flange. and few weeks later I had custom cat back made with new flanges and ss pipes. I just installed JBA Long Tube headers made for Titan and Armada. and it was a perfect fit.
