Description

Product Features:
The 31mm Type is suitable for displacement above 2400cc with exhaust pipe diameter around 56-85mm.
Use a turbine system or a blow valve to make your vehicle sound like a turbo vehicle with the turbo system or blow off valve.

About The Size:
The measured length is only the length of the whistle, not the length of the fixing frame.
Regarding size selection: please firstly measure the inner diameter of the exhaust pipe of your car.
If the turbo whistle +10mm is greater than or equal to the inner diameter of your exhaust pipe, it cannot be installed.

Installation Guide:
Loosen the screw on the turbo whistle
Insert the turbo whistle into the exhaust pipe, the larger opening facing to the inside of the muffler
Tighten the bolts so that they do not fall off when driving
Please check and re-tighten the bolts regularly

Notice:
The larger the caliber of the whistle, the louder the sound.
Some cars may have very low sound or no sound due to the low thrust of the original exhaust pipe or the modification of exhaust pipe.
The size of the sound is related to the thrust of the schedule. Too loud or too small is not a simple quality problem.

Inspection:
Professional installation is always recommended.
Blow hard into the mouth of the whistle before use.
If the whistle can be blown out, it proves that there is no problem with the whistle.
If it cannot happen after installation, it may be a problem with the exhaust thrust of the car.
