Mercedes-AMG E43 W213 Downpipes — Catless, 200-Cell & 400-Cell | M276 3.0L BiTurbo V6 | 2017–2019
YPG Motorsport downpipes for the Mercedes-AMG E43 (W213) replace the restrictive factory catalytic converters on the M276 3.0L BiTurbo V6. The factory cats are the single biggest restriction in the exhaust path — removing them unlocks faster spool, sharper throttle response, reduced EGTs, and a noticeably more aggressive V6 note with pronounced turbo whistle.
Catless vs 200-Cell vs 400-Cell — Which to Choose?
| Option | Flow | Sound | Emissions | Best For |
|---|---|---|---|---|
| Catless | Maximum — zero restriction | Loudest, raw turbo bark | No catalytic conversion | Track builds, maximum power |
| 200-Cell High-Flow Catted | Very high — minimal restriction | Aggressive with less resonance | Reduced vs catless | Street/track balance |
| 400-Cell GESI Catted | High flow — OEM+ level | Enhanced over stock, refined | Near-OEM compliance | Daily drivers wanting performance + compliance |
Power Gains with Stage 2 ECU Calibration
When paired with a YPG Stage 2 ECU calibration, the E43 delivers approximately 440–460 HP and 500–520 lb-ft of torque — a gain of +40–60 HP over the stock 401 HP. The M276 responds immediately to reduced backpressure.
