Transform your GT4 RS’s exhaust note. Our X-pipe design gives the GT4 RS the same high pitched wail as the GT3 and it’s totally plug-and-play with the factory exhaust valve system so you can quiet down the exhaust using the factory PSE button.   

Our design process started with 3D scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we decided to use our signature cast X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. We also went to great lengths to eliminate drone on this exhaust, utilizing helmholtz resonator technology to cancel out unwanted frequencies that “drone.”

SOUND:

Wondering why your GT4 RS doesn’t have the same high pitched scream of the GT3? Our Valvetronic X-Pipe is the solution! Our X-pipe design merges the two exhaust banks for an intoxicating 9000 RPM symphony. Even though this system will net you a significant increase in volume over stock, the valved design allows you to control the volume with the factory PSE (Porsche Sport Exhaust) button, quietting the exhaust note for a drone free driving experience. 

POWER:

Comparing our development car equipped with our Over Axle Link Pipes, our Vavletronic X-Pipe added 6 WHP at 8100 RPM and 9 ft/lbs of TQ at 3500 RPM.

FEATURES:

  • Fits all Porsche 718 GT4 RS 2022+ Models worldwide
  • Dyno proven power gains of 6 WHP and 9 ft/lbs of TQ
  • Saves 3 lbs / 1.4KGs compared to the factory system
  • Completely retains PSE valved exhaust functionality
  • Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
  • Helmholtz resonator technology eliminates drone
  • Incorporates our signature cast X-pipe for superior flow and exhaust scavenging
  • This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
  • Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel for optimum flow and maximum durability
  • Laser scanned and CAD designed for perfect OEM fitment using an Ametek Handyscan 700
  • No Check Engine Light guaranteed
  • Simple DIY bolt-on installation, no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
