Unlock Your RS3's Full Potential
The Mabotech 3.5" Shielded Downpipe is the single most effective bolt-on upgrade for the Audi RS3 (8V/8Y) and TTRS (8S) with the DAZA/DNWA 2.5 TFSI engine. By replacing the restrictive factory downpipe with a full 3.5" stainless steel unit, you'll see 30-50+ WHP gains when paired with a tune — with dramatically improved turbo spool, throttle response, and that signature 5-cylinder sound.
Why Mabotech?
- 3.5" Full Bore — Larger than most competitors (3"). Less backpressure = more power, especially at high RPM and on big turbo setups.
- Heat-Shielded Construction — Integrated shielding protects surrounding components from extreme EGT. Essential for the 2.5T platform.
- 304 Stainless Steel, TIG Welded — Built to last. No flex bellows failures, no cracked welds. Full stainless construction with precision TIG welding throughout.
- Direct OEM Fitment — Bolts directly to the factory turbo flange and connects to the OEM or aftermarket exhaust. No modifications needed.
- Designed for Power — Optimized for both stock turbo Stage 2 tunes and big turbo builds (M880H, hybrid setups). This downpipe won't be the bottleneck.
Estimated Power Gains
| Stock Turbo + Stage 1 Tune | +15-25 WHP |
| Stock Turbo + Stage 2 Tune | +30-50 WHP |
| Big Turbo (M880H) + Full Tune | +100-150+ WHP |
