There’s so much BS about what does and does not make power that I only trust what forum users have published independently. The facts are dropping primary cats and adding a tune adds 25 whp. IMO, all other mods: intake, catback, pulley don’t make power. I’ve proven that catback exhausts and a pulley don’t make power despite manufacture claims.
Unless someone has independently dyno’d the car (before and after) I wouldn't believe what the manufacturers publish
