What to Expect After Installation / Use

Expect a stronger exhaust presence and a more aggressive tone than stock once long tubes and the catted X-pipe are installed. Header installs are typically labor intensive on the C5 chassis; plan for professional-level installation. Calibration needs vary by setup, and tuning is commonly performed after header changes.
