QuickSilver's 'Sports' Exhaust

Porsche's factory exhaust system weighs 28 Kg (61.6 lbs) the QuickSilver 'Sports' Exhaust weighs 14.8 Kg (32.5 lbs) - Saving 13.2 Kg (29 lbs).

All 911 drivers are sensitive to the rear weight bias and know that any improvement in this area will have multiple benefits.

The QuickSilver system is constructed using T304 Stainless Steel for maximum durability.

While adhering to emission regulations the QuickSilver system realises the full potential of performance and sound. A robust sound at full throttle with respectful civility, when nescessary.

The Ultimate Sports Exhaust System for the Porsche 997 Turbo is found in QuickSilver’s ‘Titan’ Collection’.

The QuickSilver ‘Titan’ exhaust is almost a third of the weight of the standard system – reduced by 18 kilos or 38.7 lbs.

This is a remarkable weight saving particularly as the catalyst cores & shells (weighing 3.5 kilos) comprise such a large proportion of the total weight.

Importantly this weight comes off the very rear of the car and so has a profound benefit to the balance and all aspects of performance.

This system is as close to an F1 system that exists. Utilising type 625 Inconel in .7mm and .9mm thickness for tube, silencer casing, muffler internals and thicker Inconel for the balance ’flex’, bands and flanges. The heat-shields are fabricated from .5mm Titanium.

Though Inconel does not carry any inherent weight advantage over stainless steel it’s superior strength allows less (thinner) material to be used.

Plus, Inconel’s superior durability to extreme heat make it a much better material for Turbocharged and Motorsports applications – Which is why Inconel (and not Titanium) is used for F1, Indycars, Le Mans, NASCAR and just about all the top formulae.
