Description:
The OEM exhaust manifolds fitted to both the 4.3 and 4.7 V8 Vantage are horribly restrictive at medium and higher rpm, due to being made-to-a-price and the inevitable resistance imposed further upstream by the OEM catalysts.
The handmade QuickSilver exhaust package recovers the performance lost by by the compromised OEM parts, delivering an improvement of approx. 40BHP (see the performance data below), and an engine which pulls with more strength all the way to the redline.
