Product Description

Optimized design that replaces the heavy and restrictive factory side mufflers for improved exhaust flow, increased sound and weight savings. Available with or without valves. 

HELICAL VALVES

We chose to use Helical Valves on our 997.2 GT3 / GT3 RS track exhaust systems for their unprecedented quality - which have been proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, and many more. Helical valves are an integral part of our Side Muffler Bypass pipes, opening and closing with precision to control the gas flow and optimizing engine back-pressure for improved performance. Helical’s extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs and high-temperature bearings at both ends of the butterfly spindle.

FEATURES:

  • Fits all Porsche 997.2 GT3 / GT3 RS vehicles (2010-2012)
  • Saves 34 lbs from the rear of the vehicle
  • Replicates aggressive CUP car sound for the street
  • 14-16ga T304 Stainless Steel construction
  • Simple bolt-on installation
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

NOTE: For vehicles not equipped with a Porsche Sport Exhaust (PSE) / valves from the factory, a Fabspeed Valve Controller Kit is necessary to control the operation of the valves. Please choose the appropriate kit before ordering. 

 DOES MY CAR HAVE “PSE”? 

The Porsche Sport Exhaust – better known as PSE – was a factory option available on many late model Porsches. You can quickly and easily determine if your vehicle is equipped with PSE by taking a look at your center console. If your console has a button on it with an “exhaust tip” icon (see photo), then your vehicle is equipped with PSE, and you should select the PSE option when adding this product to your cart. If you do not see this button, the your vehicle does not have PSE and you should select the standard exhaust option when checking out.
