Warning: Installation of side exit without a tune or at least seeking tuner advice, may result in damage to vehicle.

Some tuners suggest to simply check for overboost before calling it "good".

All tuners have different methods, but nevertheless, seek tuner input before acting.


We at Hellfire Fabrication, are not tuners therfore we cannot offer tuning advice.
