Not much. The stock exhaust and intake are quite efficient on a stock vehicle. Also, the computer will adjust over time to these types of mods and any initial bump on the dyno will likely incur some reduction. These types of mods are for sound and looks really. Maybe 10/10 as far as any real world gain. Any benefit beyond sound might be a slightly sharper throttle response, maybe.
