How much extra horse power might I be getting for my Honda Pilot?

I drive a 2003 Honda Pilot, and I have replaced the stock exhaust system with a straight pipe all the way back to a magnaflow muffler. I have also added on a spectre cold air intake. I have noticed a small increase in response time and acceleration. I was just curious if anyone has an educated guess.

Intake and exhaust is usually good for slightly increasing the low end torque so it will feel more responsive from a start. Horsepower wise, you probably gained an honest 10 horsepower. 15 on the high end.

Probably none and you feel better about the car as you think it should be more powerful - its mental power. You could even have reduced the power output with that exhaust

You changed your torque band, but as far as adding anything, fraid not. Your lucky to get 2% power increase. I put on flowmasters today and new pipe, think i got magic hp? Fraid not

Yes, you have wasted a lot of money and you are a dumbaa$$ so what is the question?

What measuring device did you use to arrive at those figures?
