Quick answer
For a richer, patented sound and potential horsepower gains, choose the BORLA. For a more affordable upgrade with smoother flow and a simpler layout, choose the GReddy Supreme SP.
Design Philosophy: Simpler vs. Performance-Focused
The GReddy Supreme SP system simplifies the factory two-muffler layout into a single, smoother path using 76mm (3-inch) piping. This reduces weight and complexity while improving exhaust flow.
The BORLA system uses patented straight-through and multi-core technology to increase exhaust velocity. BORLA designs its systems to unleash hidden horsepower and deliver a distinctive sound profile that many enthusiasts seek.
Sound Profile: What to Expect
BORLA is known for the 'BORLA Sound of Power'—a deep, aggressive tone that is respected in motorsports. If you want a noticeable, authoritative exhaust note, BORLA delivers.
The GReddy Supreme SP is tuned for a more refined, less aggressive sound. It reduces drone while still providing a sportier tone than stock, making it a good choice for daily drivers.
Trade-offs at a glance
- Price: The GReddy Supreme SP is significantly more affordable (catalog price USD 393.30 vs. USD 846.29 for BORLA). If budget is your primary concern, GReddy offers strong value.
- Sound & Performance: BORLA offers a patented sound and potential horsepower gains; GReddy provides a smoother, less aggressive tone with improved flow. Choose BORLA for an aggressive, performance-oriented sound; choose GReddy for a refined daily-driver upgrade.
