TrackTec Valved Bypass Exhaust System. Porsche 981 Boxster / 981C Cayman ❭ FSPOR981TT
- Porsche Boxster 981 2.7L 2012-16
- Porsche Boxster 981 S / GTS 3.4L 2012-16

Our esteemed sporty Maxflo Exhaust tone with a raw, race car roar and extra power at the press of a button thanks to muffler bypass valves. One exhaust, two unique tones.
Fabspeed engineers are always tinkering, and we wanted to try something a little different. We incorporated muffler bypass valves into the inlet pipes of our Maxflo Exhaust system to unleash an additional raw, race car like tone at the press of a button. The prototype system received an abundance of attention, a positive response, and power was picked up; we're proud to offer the unique TrackTec Valved Bypass Exhaust for those looking for something special.
With valves closed, the familiar sporty, refined tone of the Maxflo mufflers offers a pleasing level of sound with no droning. With one press of the factory Sport button or Fabspeed valve remote, exhaust is free to travel unrestricted through 48mm dump tubes bypassing the mufflers. A frenzy of burbling and crackling erupts with every application of the throttle. A thunderous roar permeates the cabin at just the right volume level. Turn up the volume and turn heads to the tune of an increase of around 15whp and 19ft-lbs of torque at 4000RPM.
FEATURES:
• Fits all Porsche 981 Boxster/Cayman vehicles (2013+)
• Available with Polished or Black Chrome Deluxe Dual-Style tips or Carrera GT Style Tips
• Improves horsepower and torque by around 15 whp and 19 ft-lbs at 4000 RPM
• Saves 6 lbs from the rear of the vehicle compared to the full OEM exhaust system
• Does not trigger Check Engine Light
• Constructed from high quality 14-16ga CNC mandrel-bent T304 stainless steel for maximum performance and durability
• Noticeable improvement in sports car sound and throttle response
• Direct replacement for the OEM muffler with no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
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.

Unhappy with the dull exhaust note of his stock Cayenne, a good customer of ours requested that we unlock something special from the V6.
