Featuring an enlarged 3.5-inch design and a catless configuration, these downpipes provide a less restrictive exhaust path for enthusiasts looking to maximize exhaust flow, enhance turbo sound, and bring out more of the S58's aggressive character.\u003c\/p\u003e\n\u003ch2 data-renderer-start-pos=\"433\" tabindex=\"-1\"\u003eAdvanced Hydroformed Technology\u003c\/h2\u003e\n\u003cp data-renderer-start-pos=\"466\"\u003eThe defining feature of these downpipes is their \u003cstrong data-renderer-mark=\"true\"\u003ehydroformed construction\u003c\/strong\u003e.

The result is a precisely formed downpipe designed around the S58 platform, combining a large-diameter exhaust path with smooth contours through the bends.\u003c\/p\u003e\n\u003ch2 data-renderer-start-pos=\"1039\" tabindex=\"-1\"\u003eReduced Restriction, More S58 Character\u003c\/h2\u003e\n\u003cp data-renderer-start-pos=\"1080\"\u003eThe 3.5-inch diameter and catless configuration are designed to reduce exhaust restriction immediately after the turbochargers.
