if you get rid of the cats, like with the long tube headers, you need to adjust the A/F if you have done a tune. If not, the installation of the long tube headers will increase horsepower and reduce consumption, as it improved fill of the cylinders reducing backpressure.

I put the headers to the stock muffler so I still have back pressure and the computer did adjust the a/f to a nice flat 12 all the way through the pull.
But I still will do a tune when the snow melts.
