XForce 4" Performance Downpipe & 100 Cell High-Flow Cat for Hyundai i30 N / Kona N

Unlock the true potential of your Hyundai i30 N or Kona N with the XForce Downpipe. This performance-driven upgrade is meticulously crafted to deliver optimal exhaust flow and significant power gains. The downpipe features a massive 4" dump pipe with a heavy-duty cast top, transitioning into a high-flow metallic catalyst designed to ensure maximum efficiency and reduced backpressure.

Constructed from high-quality 409-grade non-polished stainless steel, this downpipe is built to withstand the rigors of intense performance driving and high thermal stress. The system reduces to a 3" outlet, allowing it to seamlessly connect to either your factory standard cat-back system or an XForce Performance exhaust system. This is the ultimate foundational upgrade for owners looking to elevate their N-model's horsepower, torque, and acoustic character.
