These turbo exhaust whistlers are designed to make your vehicle sound like an exhaust with a turbo system or blow off valve.
As you accellerate air is pushed through the whistler which then creates a turbo spooling sound.
Suitable to fit an exhaust which has a 44-55mm diameter.
Simple installation diagram included for easy fitting.
Important notice: The compatibility chart above is for guidance only. Please ensure that the whistler will fit inside your tailpipe as exhaust systems vary.
