Whistle sounds for me love it

Was bored and dying to buy something so went with this. Didn’t think it’d do anything other than the whistle. It totally makes a difference! Smoother throttle, more responsive, more low end torque, AND the whistle. Well worth the $.

Fairly easy to install. The promised increase in horsepower is nominal at best. My MPG has actually gone down instead of up. Have reached out to the manufacturer, but, to date, have received no response.

Perfect. With cold air intake this throttle body spacer and programmer I have a better sounding and fuel mileage truck. Works great for me ðŸ‘

I was not expecting much from this but I was expecting the whistle noise. I did not even get that.

2018 ram 2500 6.4l actually lost power on the top end.
