The Options

STuned Crackles:

This feature adds crackling/burbling sounds to your exhaust while coasting down in gear. The frequency and intensity of the sounds highly depend on your current engine speed during lift-off and most importantly: YOUR EXHAUST SETUP.

Each crackle option comes with an additional TUNE FILE.

This additional TUNE FILE will be used to Enable/Disable crackles. You must reflash from your original tune to the additional tune and vice versa.

**We have not tested all exhausts for sound quality. During testing, we found that exhaust gas temperatures have stayed relatively the same and catalytic converter temperatures had no significant increase compared to having no crackles. However, the exhaust as a whole does experience higher intensity sound/pressure waves.**
