I love this thread! Well done sir. I now have a new love and obsession with the Flowmaster cat-back you listed. :big smile:If my math correct:
Pulley gives around 5 hp
Injen CAI gives 7 hp
Exhaust should give around 8 - 10(?) hp since it is not a full exhaust with custom headers
20 hp gain
Stock Dart's whp is 112 according to K&N dyno tests so 132 hp after ....
98 torque and after around 113 ....
Is that correct?
