The S68 responds immediately to reduced backpressure with faster spool, increased boost, and a broader powerband. For the full experience, we recommend downpipes + ECU tune as a package — the tune is required to eliminate the CEL and unlock the additional timing and boost the engine can safely handle.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2023+ BMW XM (G09)\u003c\/li\u003e\n\u003cli\u003e2023+ BMW XM Label Red (G09)\u003c\/li\u003e\n\u003cli\u003eS68 4.4L Twin-Turbo V8 — all variants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Low-carbon 304 stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e TIG welded, hand finished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlanges:\u003c\/strong\u003e CNC-machined 304 stainless — laser-cut OEM mounting points\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Direct OEM replacement — bolt-on, no fabrication required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Management:\u003c\/strong\u003e Double-wall perforated heat shield wrap (factory-style)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1× pair stainless steel downpipes (catless, 200-cell, or 400-cell per selection)\u003c\/li\u003e\n\u003cli\u003eAll necessary bolts, gaskets, and clamps\u003c\/li\u003e\n\u003cli\u003eOEM-style mount points for factory exhaust retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eProfessional installation recommended.

Without a tune, you'll still see some improvement in throttle response and sound, but the CEL will remain.\u003c\/p\u003e\n\n\u003ch4\u003eWhat's the difference between catless and 200-cell?\u003c\/h4\u003e\n\u003cp\u003eCatless removes the catalytic converter entirely for maximum flow and power. 200-cell high-flow cats retain some catalytic conversion while still flowing significantly more than the factory 600+ cell units. Choose catless for track builds, 200-cell for aggressive street use, or 400-cell GESI for maximum compliance.\u003c\/p\u003e\n\n\u003ch4\u003eHow long does installation take?\u003c\/h4\u003e\n\u003cp\u003eApproximately 3–4 hours with proper lift access.
