Well for one you will have flames so hopefully they are directed down and out, and may cause a CEL from the increase in exhaust flow compared to stock... Why not go headers and catback....? Back pressure is more a myth for making things :"run right". My car is a LS3 I get enough decel popping from the fuel cutoff anytime I go from gear to gear down , or let off throttle to worry if I had cutouts that I would have to have it altered to try to remove it in the tune and run richer so I would not be the backfire mobile.....shooting flames under my seat is not what I want.... Some people have done this maybe they will chime in. But if they went with stock exhaust.....
