Atmospheric bypass trumpet

  • Sale
  • Regular price $65.00
Tax included. Shipping calculated at checkout.

UPDATE July 2021 - Due to overwhelming demand, we are having this made from smooth ABS plastic. This will increase the price, as they will cost more to make.

We expect to see them arrive early August.

-NOTE, we are discontinuing the supersonic version, as the whistler has been tweaked to be the best of both worlds.


Increases the whistle noise from the supercharger at idle, with a nice sublte whoosh sound when backing off the throttle under boost. 

Low profile, discreet with a great sound.

5 minute install, comes with block off cap for airbox.

Re-route the hot waste air out of the system and vent it to atmosphere.
This will lower intake temps and increase available horsepower.

Instructions included.

Made from 100% solid PLA 3D print filament to keep price low.
