Boss 302 Exhaust - Sides & Sounds

The super-restrictive discs feature holes for exhaust gas and sound discharge. From a sound perspective, the Boss-modified GT maintained a fairly quiet rumble with the restrictors in place. However, once Ricardo removed the plates, the 'Stang took on the exhaust note of a real-deal Boss 302.
