I added the headers and a NST pulley and went from 303 to 310 rwhp. SAE.
it made 301 with the berk cats, stillen CBE stillen intake and my own cobb map.
Car was a lot louder. It did lose some hp between 5000 to 6400 rpm ( lost about 4 to 5 and some torque) but it made almost 9 to 10 more at 7500 to 7600 rpm. It also made more power to 8100 rpm.
