Constructed from high-grade T304 stainless steel, this single 102mm mandrel-bent midpipe replaces the restrictive OPF\/GPF section with a free-flowing x-pipe design—delivering a sharper, louder exhaust tone and reducing backpressure for improved throttle response.\u003c\/p\u003e\n\u003cp data-end=\"973\" data-start=\"767\"\u003eThis system is designed for drivers seeking a more aggressive, motorsport-inspired sound and is ideal when combined with a Stage 2 ECU remap or OPF\/GPF delete module.

Instead of balancing between engine banks, this X-pipe helps smooth turbulent flow created by the turbochargers and previous bends in the system. The result is a sharper, higher-pitched exhaust note with reduced rasp—ideal for the S58’s naturally aggressive tone. This makes it a perfect choice for drivers looking to enhance volume and clarity without introducing excessive drone or harshness.\u003c\/p\u003e\n\u003chr data-end=\"1223\" data-start=\"1220\"\u003e\n\u003ch3 data-end=\"1244\" data-start=\"1225\"\u003e\u003cstrong data-end=\"1242\" data-start=\"1225\"\u003eKey Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-end=\"1556\" data-start=\"1245\"\u003e\n\u003cli data-end=\"1307\" data-start=\"1245\"\u003eDeletes OPF\/GPF for enhanced sound and reduced restriction\u003c\/li\u003e\n\u003cli data-end=\"1370\" data-start=\"1308\"\u003eLarge 102mm (4”) mandrel-bent stainless steel construction\u003c\/li\u003e\n\u003cli data-end=\"1425\" data-start=\"1371\"\u003eNon-resonated x-pipe layout for an aggressive tone\u003c\/li\u003e\n\u003cli data-end=\"1490\" data-start=\"1426\"\u003eDesigned for use with Stage 2 remap or OPF\/GPF bypass module\u003c\/li\u003e\n\u003cli data-end=\"1556\" data-start=\"1491\"\u003ePrecision-engineered fitment for G80\/G81 M3 \u0026amp; G82\/G83 M4 models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"1561\" data-start=\"1558\"\u003e\n\u003ch3 data-end=\"1632\" data-start=\"1563\"\u003e\u003cstrong data-end=\"1581\" data-start=\"1563\"\u003eCompatibility:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp data-end=\"1632\" data-start=\"1563\"\u003eBMW G8X Series (OPF\/GPF-equipped models only):\u003c\/p\u003e\n\u003cul data-end=\"1818\" data-start=\"1633\"\u003e\n\u003cli data-end=\"1654\" data-start=\"1633\"\u003e\u003cstrong data-end=\"1652\" data-start=\"1635\"\u003eBMW G80 M3 Saloon (2021+)\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli data-end=\"1677\" data-start=\"1655\"\u003e\u003cstrong data-end=\"1675\" data-start=\"1657\"\u003eBMW G81 M3 Touring (2023+)\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli data-end=\"1698\" data-start=\"1678\"\u003e\u003cstrong data-end=\"1696\" data-start=\"1680\"\u003eBMW G82 M4 Coupé (2021+)\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli data-end=\"1725\" data-start=\"1699\"\u003e\u003cstrong data-end=\"1723\" data-start=\"1701\"\u003eBMW G83 M4 Convertible (2021+)\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli data-end=\"1771\" data-start=\"1727\"\u003e\n\u003cstrong data-end=\"1743\" data-start=\"1729\"\u003eSSXBM1336:\u003c\/strong\u003e Fits OEM axle-back system\u003c\/li\u003e\n\u003cli data-end=\"1818\" data-start=\"1772\"\u003e\n\u003cstrong data-end=\"1788\" data-start=\"1774\"\u003eSSXBM1338:\u003c\/strong\u003e Fits Milltek axle-back system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"1823\" data-start=\"1820\"\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1953\" data-start=\"1825\"\u003e\u003cem data-is-last-node=\"\" data-end=\"1953\" data-start=\"1825\"\u003eNote: Cutting may be required when fitting to the OEM system.
