The tip installs in your exhaust opening and creates a turbo sound under acceleration. On certain cars the turbo sound tip can even create a blow off valve sound under heavy acceleration. These tips are easy to install on any car or truck, made from high quality lightweight aluminum. The pressure blowing out of your exhaust creates a spooling sound with this product installed. This sound is similar to how a real turbo works. In some cases, during shifts - back pressure is drawn through the unit creating a "psssssssssssshhhhhhhhhhhhht" type of sound similar to a blow off valve. The results will vary depending on your car the higher the RPM, the higher the pitch.
