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. We're proud to now 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 controller remote, the exhaust is free to travel unrestricted through the 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.

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. 


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.

    Great sound, one flaw

    Posted by Howard Schaefer on 28th Jun 2018

    Had this installed recently on my Boxster. The sounds of closed and open are just what I wanted especially on the open road. Riding at around 3-4000 rpm with the valve open and accelerating somewhat less than wot produces a great wailing sound. Accelerating wot with the valve open in any case is kind of coarse sounding. The one flaw I find is that the system returns to the open position so that every time the car is started the sound is quite loud. Some may like this but I feel it should be the other way around. This is not changeable. Otherwise quality is tops!

    Music to my ears

    I had this system installed on my 2008 Cayman Base and it woke the car up. I love both sounds. But when you hit the pedal with the valves open.. People take notice and most say that does not sound like a stock Porsche. And then it's just the look of the system from the back of the car. You know that you're looking at a serious exhaust system. Definitely a game changer for my Cayman.
