Show original supplier description
The Xforce 4" High-Flow Downpipe is engineered to significantly boost the performance of your Hyundai i30 N or Kona N. Key features include a robust 4-inch dump pipe with a cast top for maximum turbocharger efficiency, and a 200-cell high-flow metallic race catalytic converter that optimizes emissions flow without hindering performance. The downpipe is constructed from heavy-duty, non-polished stainless steel, ensuring durability under aggressive driving conditions. It tapers down to a 3-inch outlet, allowing for seamless bolt-on integration with your factory cat-back exhaust or an Xforce Performance exhaust system. Installation of this downpipe requires an ECU tune post-installation. This is crucial for fully optimizing performance, ensuring correct air-fuel ratios, and maintaining overall reliability.
