Finally ditching the glasspacks! The 327 Small Block in the Nova Wagon needs a wake-up call, so today we're swapping to the FlaShark Super 10s for that aggressive, single-chamber tone.

About this Install:
The old glasspacks were classic, but they lacked the "snap" I wanted. I'm looking for that hollow, aggressive idle that sounds like a serious hot rod but doesn't drone me out of the cab. These single chambers are budget-friendly, compact, and should flow a ton better.

🚩The Setup (1965 Chevy Nova Wagon):
Engine: 327ci Small Block Chevy (L79 Cam, 461 Camel Hump Heads)
Intake: Edelbrock Air Gap & Flat Top Pistons
Headers: GComp Long Tube Chassis Headers
Old Exhaust: Glasspacks (2.5" out to behind rear tire)
New Exhaust: FlaShark Single Chamber (Super 10 Series)
