Overview

The QuickSilver AS307S is a set of secondary catalyst replacement pipes designed for the Aston Martin DB9 (2004-16).

Show original supplier description
The QuickSilver AS307S secondary catalyst replacement pipes are engineered as a direct fit for the Aston Martin DB9 models produced between 2004 and 2016. Crafted from durable T304 stainless steel and backed by a 25-year corrosion guarantee, these pipes are built to last. Dyno tests have confirmed an improvement of 16bhp, increased mid-range torque, and noticeably improved throttle response. The accelerated gas flow also helps draw heat away more efficiently, which is particularly beneficial for tuned engines. Installation is straightforward as they are 'plug & play,' requiring no retuning or other modifications. The weight saving is substantial, with these pipes weighing 3.6 kilos (approximately 8 lbs) compared to the OEM parts' 7.2 kilos (approximately 16 lbs), resulting in a saving of 3.6 kilos. QuickSilver has focused on producing a crisper exhaust note with these 'Race' catalysts, complementing the overall improved response. The product requires no modifications for installation, ensuring a seamless integration into the existing exhaust system.
