Product Description

Improves exhaust tone and saves weight by replacing the factory center muffler with a lightweight x-pipe. The 991 Carrera Valvetronic Center Muffler Bypass X-Pipe makes a great compliment to either the factory PSE side mufflers or to Fabspeed's Maxflo Performance Side Exhaust System. With valves open and closed you'll experience greater volume and a smoother tone than the factory Porsche exhaust system.

FEATURES:

  • Fits Porsche 991 Carrera 3.4L (With PSE) and Carrera S 3.8L vehicles (With or Without PSE) 2012-2016 - Specify Model Above
  • Greatly improves horsepower and torque
  • Saves 12 lbs. versus the factory center muffler
  • Dramatic improvement in sports car sound and power throughout the RPM range
  • Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
  • Direct bolt-on replacements for the factory center muffler (3.8L NON-PSE Vehicles include a Valve Controller to operate valves)
  • 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. 

NOTE: This Valvetronic Muffler Bypass X-Pipe is compatible with all 991 Carrera 3.8L models With or Without Porsche Sport Exhaust (PSE) but the NON-PSE equipped cars will include a Valve Controller.

 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.
