The Options


STuned Crackles:

This feature adds crackling/burbling sounds to your exhaust when lifting off the throttle and coasting down in gear. On catless setups there can be flames. The frequency and intensity of the sounds highly depend on your current engine speed during lift off and most importantly: YOUR EXHAUST SETUP. We recommend at least an aftermarket downpipe. 

When crackles are purchased a separate TUNE FILE is sent containing the crackles.

This additional TUNE FILE can 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 nor do we have any data on the long-term effects of this feature on the catalytic converter. However, we have found that exhaust gas temperatures have stayed relatively the same and catalytic converter temperatures had no significant increase compared to having no crackles.**
