Over Axle Link Pipes For Porsche 718 Cayman GT4 RS (2023-2025) ,Boxster Spyder RS (2024) Models.

Unleash GT3 Sound, Increase Power, and Save Weight with a Simple Bolt-On Upgrade

Transform the sound and performance of your Porsche 718 GT4 RS or RS Spyder with Fabspeed's Over Axle Link Pipes. This straightforward modification replaces the restrictive factory over-axle pipes, delivering a significantly throatier and more aggressive GT3-inspired engine note, increased power, and notable weight savings. Just like the regular GT4, these link pipes represent an ideal first step in enhancing your Porsche's driving experience.

Our engineering process began with a precise 3D scan of the entire OEM exhaust system using our CREAFORM 700 Handscan. This allowed us to create a complete Solidworks 3D model, ensuring a perfect bolt-on fitment to OEM standards in both design and execution.

SOUND:

Prepare to be amazed by the richer, more aggressive tone emanating from your GT4 RS or RS Spyder. These Over Axle Link Pipes unlock a significantly stronger and throatier exhaust note, bringing out the true character of your flat-six engine. The increase in volume and tonal depth is substantial yet remains perfectly balanced for exhilarating driving without being overly loud. Installation is incredibly simple: just remove the rear wheels and the stock pipes, bolt on the Fabspeed link pipes, and you're ready to go – no tuning required!

POWER:

Even with a completely stock exhaust system and no ECU tune, our Over Axle Link Pipes deliver impressive dyno-proven power gains. We recorded an increase of 30 horsepower at 4750 RPM and 34 ft-lbs of torque at 4750 RPM, translating to an estimated 33 horsepower gain at the crank! Peak horsepower also saw a rise from our baseline of 456 WHP to 474 WHP, and peak torque increased from 330 ft-lbs to 341 ft-lbs. Refer to our dyno graph for detailed results. Experience clean and green power, developed with Fabspeed Motorsport USA's 30 years of expertise in air-cooled and water-cooled flat-six engines, delivering high-pitched sports car sound and tangible performance.
