304ss Valved Catback Exhaust for Porsche 911 997.1 997.2 Carrera 4S
Upgrade your Porsche 997 Carrera / Carrera S with the STRATEC Valved Sport Exhaust System in T304 Stainless Steel, engineered to deliver a sharp, high-revving motorsport-inspired sound with durability for long-term street and performance use.
Featuring equal-length performance headers, a free-flow X-pipe, and valved side mufflers, this complete exhaust system transforms the 997’s tone into a clean, aggressive, F1-inspired sound profile. With valves open, it produces an intense, track-focused exhaust note. With valves closed, volume is reduced significantly for a more refined and comfortable daily driving experience.
This is a full-system upgrade — not an axle-back — ensuring optimized flow, tone balance, performance response, and reliability.

Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
