Product Details
The Flat 6 Motorsports Over Axle Pipes (OAPs) for the 718 GT4 RS and Spyder RS, provide a high flow and smoothed exhaust flow design. These are a direct factory replacement and bolt on solution, making it an easy to do install for most skill levels.
The Flat 6 Motorsports over axle exhaust pipes are engineered to provide optimal flow and maximum performance. Our GT4 over axle pipes are made from T-304 Stainless Steel or optional Titanium and feature a proprietary heat-shielding technology to insulate heat inside of the piping. This dramatically reduces heat transfer to key components like rear brake lines, PASM connectors, axles and suspension. The OAPs are meticulously TIG welded for a high quality finish and lifelong durability. The stainless steel version shave over 12 lbs (roughly half the weight) from the factory pipes, while the titanium are nearly half the weight of the stainless steel version, saving off over 18 lbs.

- Direct Factory Replacement
- Significant Exhaust Flow Rate Enhancement
- 20+ HP Gains
- Weight reduction of 18lbs in Titanium or 12.2lbs in Stainless Steel compared to the factory pipes
- Improved Sound
- Easy to Install
- Includes New High-Grade Stainless Bolts & Locking Nuts
Engineered
Porsche brought over the GT3 powerplant and had to incorporate a modular design for various global emission requirements. This led to a factory over axle pipe that provided massive restriction.
After studying and analyzing this design, Flat 6 Motorsports developed a solution that utilized the factory concept but enhanced the bends and eliminated restrictive elements of the factory design. We achieved this by utilizing 80mm (~3") tubing with smoothed mandrel bends. Replacing the restrictive factor canister with a smooth flowing design ensures optimum exit flow to the muffler section. Advanced simulation software showed this design to most efficiently distribute exhaust flow.
Materials
We chose to use proven high-grade materials including T-304 Stainless Steel or optional Titanium and an advanced proprietary heat shield that is welded and integrated to the piping. This provides great structural integrity while reducing weight and limiting heat transfer from the piping. The increased flow and reduction in restriction also lowers exhaust gas temperatures (EGT).
Installation
We include the high-grade stainless steel hardware to make this job a simple DIY for consumers who are comfortable installing exhaust work. This is a direct factory replacement and can be installed in less than 2 hours.
