Description
QuickSilver’s Manifolds and Race Catalysts transform the V8 Vantage’s restricted OEM exhaust into a high-performance system. Drawing on expertise as an Aston Martin Racing partner, QuickSilver engineered these components to recover lost performance, deliver a visceral GT4 soundtrack, and unlock the true potential of your V8.
The OEM manifolds and catalysts impose significant resistance at medium to high RPM. This handmade QuickSilver package eliminates those compromises through meticulous design and precision manufacturing.
Key Features:
- 4>1 equal-length primary pipes with bespoke sequential collector cone optimizes exhaust gas scavenging
- 2mm 316 grade stainless steel primary pipework ensures exceptional durability
- 200 cpsi metallic race-catalysts reduce backpressure and restriction
- Laser-cut flanges deliver consistency across all components
- All joints and bends fully purge-welded with inert gas prevents cracking, corrosion, and deformation
- Reduces overall system weight by 18 kilos
Performance Notes:
- Approximately 40 BHP improvement over OEM manifolds
- Enhanced engine pull all the way to redline
Testing & Validation:
- Extensively tested at Millbrook proving ground under thermal acceleration cycles
