A downpipe from HG Motorsport can be used as a complete replacement for the standard component. Precise fitment and high-quality materials make this a high-quality product. Optimising the diameter, pipe routing and\/or catalytic converter can significantly reduce the load on the turbocharger. Lower back pressure and reduced thermal load provide a noticeable increase in torque and power, earlier response and, at the same time, improved durability.<\/p>\n<h3>Technical details<\/h3>\n<ul>\n<li>2 \u00d7 70 mm (2.75\u2033)<\/li>\n<li>Available without a catalytic converter, with a 100-cell sports catalytic converter, with a 200-cell sports catalytic converter or with a Bull-X 200-cell EOBD sports catalytic converter by HJS<\/li>\n<li>Made from stainless steel<\/li>\n<li>Plug\u2019n\u2019Play solution<\/li>\n<li>Precise fitment and easy replacement of the original component<\/li>\n<li>High-quality materials<\/li>\n<li>Made in Germany<\/li>\n<li>Flow-optimised for increased performance<\/li>\n<li>Improved durability and response<\/li>\n<li>Optimal exhaust gas evacuation<\/li>\n<li>No disruptive edges at the transitions<\/li>\n<li>Designed and tested using computer simulations and on a rolling road<\/li>\n<\/ul>\n<p><strong>Note:<\/strong> Downpipe versions without ECE approval may cause the engine warning light to illuminate.<\/p>\n<p><strong>Road use:<\/strong> Only the Bull-X 200-cell EOBD sports catalytic converter by HJS with EG approval is permitted for use on public roads.
