Mercedes C43/E43 Catless Downpipes | WSTN Performance (M276 W205/W213)

Stop choking the M276. The factory downpipe was never meant to keep up with what AMG built. WSTN Performance catless downpipes for the Mercedes-Benz M276 3.0L twin-turbo V6 platform. Engineered for direct OEM-spec replacement on the W205 C-Class (C43, C400, C450) and W213 E-Class (E43, E400, E450), including the S213 wagon, C238 coupe, and A238 cabriolet. Mandrel-bent 304 stainless steel, TIG-welded, every set personally quality-checked at our Perth WA facility before dispatch worldwide. Why Upgrade? ✓ Acoustic Transformation: Lets the M276 sound the way it was engineered to. Deeper twin-turbo V6 note under load, civilised at idle. ✓ Performance Gains: Reduced backpressure improves turbo spool and throttle response across the rev range. ✓ Direct Bolt-On: Fits factory exhaust manifold mounting points. No cutting, no welding, no flex. ✓ Mandrel-Bent Construction: Smooth flow path with no kinks or pinch points where stock pressing introduces them. ✓ Built for Both Banks: Matched left and right pipes for the M276's V6 architecture. Even flow, even tone.
