Turbo whistler M 37-48mm

THE WHSITLE MOUNTING DIAMETER: 37-48 MM

After installing the whistle, during "adding gas" or fast driving, the car makes a very effective sound, similar to the effect using NITRO.

The whistle is mounted inside the end of the muffler

VERY EASY ASSEMBLY - JUST PULL THE WHISTLE TO THE MUFFLER TIP AND TIGHTEN.
