The ultimate Sports Exhaust system for the Porsche GT3 inc RS & CS QuickSilver were approached by a well known specialist in racing and track-day Porsche, to develop a complete SUPERCUP exhaust system for enthusiast customers.
KEY FEATURES: More Power +20bhp Less Weight - to lose over 20kgs (~44lbs) from the rear of the car. Ease of fit & no loss of ground clearance > All in a compact volume. Great Sound - but to enable compliance with most track-day venues - A tall order! Motorsports Look. Appropriate Sound - about 105dB > but reduced further with removable Titanium cans.
An ambitious project, requiring new materials technology, manufacturing methods, component integration and constant testing.
The factory exhaust includes five muffler casings, 2 x Cats, 2 x side mufflers and 1 x rear muffler. QuickSilver's brief was to distil these into 1 x casing & similar to the system produced by Porsche's Motorsport Dept for their international one-make racing series.
Drawing their constant racing experience our partners were able to provide technical input and testing facilities.
Throughout the development period the system was evaluated both at our partner's in-house test facilities and on the track. Each time refinements were included in the overall design to create a fantastic system worthy of the Porsche name.
QuickSilver system includes: Manifolds with equal-lenght primary pipes of the appropriate bore for optimum power. Single rear silencer casing housing integral 200 cpsi RACE catalytic converters. Provision for fitting of OBD2 exhaust sensors measuring the exhaust gas composition before and after the Cats on both cylinder banks.
This sports exhaust set conveys the sound of power, presence and natural sporting presence the 911 needs. Built with a large diameter chamber bypass pipe the engine note changes with more aggressive throttle.
