BMW B58 (G20 G30 G01 G29) & Supra A90 (2015-2026) Performance Downpipe - Vortex

BMW B58 (G20, G30, G01, G29) & Toyota Supra A90 Performance Downpipe - Vortex®

Unlock the True Potential of the "Modern 2JZ"

The BMW B58 engine has earned its reputation as a tuning masterpiece. But even a legend can’t breathe through a straw. The factory downpipe, choked by a massive, high-cell density catalyst, is the single biggest bottleneck for both power and sound.

Vortex® has engineered the ultimate high-flow downpipe solution to eliminate backpressure, significantly reduce turbo lag, and deliver the crisp, aggressive straight-six soundtrack that these machines were born to have. Whether you're chasing lap times or 1/4 mile records, our downpipe is the foundation for your Stage 2 build.

### Vehicle Compatibility & Fitment

Precision-designed for a 100% bolt-on fitment across the B58 engine platform:

### Technical Highlights

• Maximizing Power & Efficiency: By optimizing exhaust gas velocity, our downpipes allow the B58’s twin-scroll turbo to spool up significantly faster. Pair this with a Stage 2 ECU tune for dramatic gains in both peak HP and torque.

• Signature Straight-Six Soundtrack: Transforms the muted, vacuum-like factory note into a muscular, high-definition growl. Expect sharp "pops and bangs" and that iconic high-frequency mechanical rasp.

• Premium Material Engineering:

  • T304 Stainless Steel: Precision mandrel-bent stainless steel for maximum flow and lifelong corrosion resistance under high thermal loads.

  • Grade 5 Titanium (Optional): For the ultimate weight-conscious build. Significantly lighter than stock and provides an exotic, sharper metallic tone.

• Artisanal Craftsmanship: Every Vortex® system features our signature hand-laid TIG fish-scale welding. This ensures maximum structural integrity while looking like a work of art under your chassis.

• Heat Management Optimization: Designed using 3D laser scans to ensure perfect clearance and improved heat dissipation, protecting sensitive engine bay components.
