Well no i didnt dyno it but there has to be some gain to it
Not with a d-series there isn't. You are going to need a LOT more than simple cheap bolt ons to gain power with that commuter. There is a reason people swap to bigger motors, or put turbos on.
Unfortunately the cold hard truth is that you just changed the sound, absolutely no discernible power was added. Especially not one that is just sucking in all that hot air from on top of the motor.
It's good that you want to wrench on your car
, but don't fool yourself into thinking cheap bolt ons are going to do anything in the way of good power to the wheels just because it says so on the box.
