The VRP Valvetronic Exhaust System for the Porsche 991 GT3 and GT3 RS is engineered for owners who demand uncompromising quality and an enhanced driving experience. Crafted from premium T304 stainless steel with precision TIG-welded construction, this exhaust is built to withstand the extreme thermal and mechanical loads that Porsche’s naturally aspirated 4.0L flat-six is known to deliver. Each component is CNC-bent and robotically finished to ensure exacting tolerances and a factory-level fit that integrates seamlessly with the OEM rear valence and factory mounting points.

One of the defining features of the VRP system is its integrated valve control technology, which allows you to adjust the exhaust character at the touch of a button. With the valves closed, the system maintains a subdued, refined tone that is perfect for early morning drives or long-distance cruising. Open the valves, and the VRP exhaust completely transforms the car’s demeanor, releasing the full resonance of the 9,000 RPM flat-six. The exhaust note becomes sharper, more aggressive, and race-bred, echoing the heritage of Porsche’s GT motorsport division.

This valved design not only gives you control over the sound experience but also optimizes exhaust gas flow for improved performance when the valves are open. Reduced backpressure and smoother flow paths enhance throttle response and allow the engine to breathe freely. The result is a driving experience that feels more connected and visceral, whether you're carving up canyon roads, attacking a circuit, or enjoying a spirited weekend drive.

From its mirror-polished tips to the harmonically tuned internal chambers, the VRP Valvetronic Exhaust System delivers a balance of performance and sophistication worthy of the Porsche GT3 and GT3 RS nameplates. It is the ideal choice for owners who want the flexibility to enjoy a refined OEM-like tone or unleash the unfiltered, motorsport-inspired soundtrack that makes the 991 GT3 platform so special.

– "Track-Ready Sound and Performance"

"I’ve tracked my 991.2 GT3 extensively, and this VRP Valvetronic system completely transformed the car. With the valves open, it’s like driving a Cup car — raw, high-pitched, and exactly what you want when you’re flat-out. Throttle response is noticeably sharper, and the weight savings over stock is a nice bonus. Zero drone on the highway too. Worth every penny for anyone serious about driving their GT3 the way Porsche intended." – Mark T., GT3 Owner

– "Quiet When You Want, Wild When You Don’t"

"The valve control is a game changer. In normal mode, the car is quiet enough that I don’t wake up the neighborhood at 6 AM. But open the valves, and it absolutely rips — the flat-six scream is addictive. The build quality is superb, and the fitment was perfect. This is exactly how the car should have sounded from the factory." – Andrew 

 – "Best Mod for Daily + Weekend Drives"

"I almost daily my GT3, so I wanted an exhaust that wasn’t obnoxious in traffic but could come alive on the weekend. This VRP system nails it. Valves closed, it’s civil and refined. Valves open, it’s pure motorsport spine-tingling wail past 8,500 RPM. Couldn’t be happier." – Kevin  991.1 GT3 Owner

– "Quality That Matches the GT3’s Pedigree"

"I’ve owned Akrapovic and Capristo systems on other cars, and the VRP exhaust is right there in terms of craftsmanship and sound. The welds and materials are top-notch, and it feels built to last. The dual personality — quiet when needed, absolutely ferocious when opened up — makes every drive special." – Daniel R., GT3 RS Owner
