Replacing the restrictive factory dual-pipe layout with a massive single 4-inch merge dramatically improves exhaust gas flow and eliminates the unwanted high-RPM rasp inherent to the S58 engine platform.\u003c\/p\u003e\n\u003cp\u003eManufactured entirely from high-grade, TIG-welded stainless steel, this resonated performance mid-pipe delivers a significantly deeper, highly aggressive exhaust note while utilizing an integrated high-flow resonator to smooth out harsh frequencies. To guarantee a perfect installation, the kit includes a custom-engineered heavy-duty replacement chassis under-brace designed to clear the enlarged 4-inch pipework while maintaining total structural rigidity.\u003c\/p\u003e\n\u003cp\u003ePart Number: SLN_G80_MID_4_R\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan role=\"text\"\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e– Massive 4.0-inch (101.6mm) single center section\u003cbr\u003e\n– Integrated high-flow resonator to eliminate cabin drone and harsh tones\u003cbr\u003e\n– Crafted from premium heavy-gauge TIG-welded stainless steel\u003cbr\u003e\n– Mandrel-bent piping ensures smooth exhaust velocity\u003cbr\u003e\n– Direct bolt-on fitment to OEM downpipes and rear axle-back system\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan role=\"text\"\u003eBenefits\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e– Deep, aggressive, and highly refined straight-six exhaust note\u003cbr\u003e\n– Drastic reduction in backpressure for improved turbo response\u003cbr\u003e\n– Completely eliminates the notorious S58 mid-range and high-RPM rasp\u003cbr\u003e\n– Included custom clearance under-brace prevents underside rattles and rubbing\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan role=\"text\"\u003eDimensions\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e– Main Pipe Diameter: 4.0\" (101.6mm)\u003cbr\u003e\n– Material Thickness: 1.5mm heavy-gauge stainless steel\u003cbr\u003e\n– Configuration: Resonated single mid-pipe merge section\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan role=\"text\"\u003eFAQ\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this mid-pipe trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. Because this high-flow single mid-pipe deletes the restrictive factory secondary components, it will alter the variance readings on the factory sensors and trigger a CEL. A proper ECU tune, OPF delete module, or CEL deleter will be required to code it out.\u003cbr\u003e\u003cbr\u003e\n\u003cstrong\u003eQ: Is cutting required for installation?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. Like almost all aftermarket mid-pipes for this platform, you must cut the factory one-piece exhaust system to slip and clamp this unit into place.
