Give your 997 the voice it should have worn from day one. The Yonristic system replaces the bulky stock center canister with a muffler-less X-pipe and tuned high-flow cans, feeding compact side mufflers and quad tips for a factory+ soundtrack—deep and composed at cruise, razor-clean and aggressive when you push. Built from 304 stainless or aerospace-grade titanium, 3D-scanned for a perfect fit, and fully PSE-valve compatible, it sheds weight, sharpens response, and unlocks real 911 character without the drone.

Key Features

Vehicle Fitment

Design & Sound

True Center Cross: Positioned at the pulse-exchange sweet spot, the X equalizes pressure between banks, improving scavenging and sharpening the engine’s attack as revs rise.
Tuned High-Flow Cans (center): Sized and placed to knock out the 997’s boom frequencies; they smooth the note under cruise while keeping the exhaust path free-flowing.
Compact Side Mufflers: Unpacked, straight-through internals maintain velocity and give the car a rich, classic 911 timbre at light load with a fierce wail when you lean on it.
No Drone Tuning: Geometry and can volumes are modeled around cabin resonance zones, so highway cruising stays calm while exterior character remains aggressive.

Valve Control — OEM behavior, plug-and-play

We retain the factory PSE valve locations and actuator mounts; on PSE-equipped cars the behavior is fully preserved. For non-PSE cars, our optional remote valve kit gives you two characters on demand—refined for long trips, or wide-open for back roads.

Performance

On a healthy 997.1, a well-designed X-pipe cat-back typically delivers +8–12 whp and +8–12 lb-ft with noticeably crisper throttle response. Pairing our system with 200-cell sport cats and a quality ECU calibration commonly lifts total improvements into the +15–25 whp range, with a broader, cleaner pull to redline. The headline, however, is tone quality and weight: deleting the bulky center canister drops mass and replaces the muted stock voice with a sharp, classic flat-six cry.

High-Quality Construction and Design

The VANTA Edition is crafted from high-quality materials ensuring durability and longevity. Its sleek design complements the Corvette's aesthetics, adding a stylish touch without compromising functionality.
