Vibrant SS Bellow Assembly w/ Solid Liner 4in Inlet/Outlet ID x 4in Overall L Electro Polished - Universal Fit
Vibrant SS Bellow Assembly with Solid Liner delivers vibration isolation for 4-inch performance exhaust systems on turbocharged cars, diesel trucks, and custom builds. Engineered from T304 stainless steel, this electro polished flex coupling absorbs engine movement to protect manifolds, downpipes, and connected parts from stress and fatigue. It extends component life in high-heat, forced induction applications.
Key Features
- T304 Stainless Steel Construction: Provides enduring strength and resistance to corrosion in extreme exhaust environments
- Electropolished Finish: Creates smooth surface for reduced buildup and enhanced durability against heat and road salt
- Solid Inner Liner: Blocks exhaust leaks, minimizes noise, and reinforces the bellows against collapse under pressure
- 4 Inch Inlet/Outlet ID: Matches standard 4in performance piping for seamless integration in turbo downpipes and exhaust kits
- 4 Inch Overall Length: Compact size fits tight spaces while maintaining full flex range for vibration damping
Product Notes
- Pair with V-band clamps or flanges for secure, leak-free connections
- Inspect periodically for wear in high-vibration setups
- Packed in protective tube to prevent shipping damage
Installation Notes
- Professional installation recommended.
- Align inlet and outlet precisely before clamping to avoid binding
- Compatible with standard 4in V-band flanges and marmon connections
