My experience has been that the claimed HP increases by the manufactures does not match what the Dyno says. When I put the fabspeed cat bypass on my 2.7L I may have picked up 2 hp on the dyno. But the intake and cat bypass offer a nice improvement in the sound of the car to my ear, and sure make it sound like the car is going faster.
