Mercedes C63 AMG Exhaust Manifolds and Downpipes | WSTN Performance (M156 W204/S204/C204)

Headers and downpipes together. The M156's factory exhaust restrictions start from the cylinder head. This addresses them at the source. WSTN Performance T304 stainless exhaust manifolds and downpipes for the 2008-2015 Mercedes-Benz C63 AMG. Full upper system replacement covering both cylinder banks from the head flanges to the catalytic converter inlets, quality-checked at our Perth WA facility before dispatch worldwide. Why Upgrade? ✓ Full Upper System Coverage: Manifolds and downpipes together remove every restriction between the cylinder heads and the mid-pipe. Most of the M156's sonic and performance headroom lives in this section of the exhaust. ✓ Larger Primary Tubes: The factory manifolds use conservative primary sizing and tight bends. T304 stainless mandrel-bent primaries improve flow velocity and reduce restriction at the head. ✓ T304 Stainless Construction: Dimensionally matched to the W204/S204/C204 chassis. Built to retain factory fitment geometry on the M156's tight engine bay. ✓ Hand Built to Order: Each set is built to your order from Perth WA. Not pulled from stock.
