your gains will vary, depending on where its located and what catback you have. i gained 2 hp with it open- and i have a magnaflow catback.
if you have a stock catback on there, i would say that the cut out would gain you more hp as opposed to having a magnaflow or a LM on it, with the cut out open
im going with a stock catback to be sneaky

i was thinking about doing 2 cutouts after the headers one day.
