Active Autowerke Catless Downpipe – BMW X5M / X6M

OVERVIEW

Hand made Active Autowerke Signature S63 downpipes for the twin-turbo V8 BMW X5 M and X6 M. Turbo impeller wheel speed is largely limited by exhaust back pressure, so these downpipes are built with the least restriction possible — full 3" piping throughout with the fewest bends possible — letting the turbos spool faster for quicker revs, sharper response and increased horsepower. Construction is 304 stainless steel, hand made in house for a robust, durable exhaust with the longevity to match.

• 304 stainless steel construction, hand made in house

• Full downpipe exhaust support braces to relieve load bearing stress

TECH RESOURCES

Additional Parts Required

• Off-road flash tune — required. On the stock tune these catless downpipes will set a check engine light. A tune with the catalyst efficiency monitors removed is required.
• Bootmod3 S63TU Tune – BMW M5 / M6 / X5M / X6M (F1x) — covers the F85 X5 M and F86 X6 M. bootmod3 flashing requires an OBD-to-Ethernet (ENET) cable, or the bootmod3 WiFi adapter offered as a bundle option on that listing.
• Neither MHD nor bootmod3 publishes support for the 2010–2014 E70 / E71 S63. Contact Speed Logic for tuning options on those cars.
• Your vehicle VIN is required at the time of order so Active Autowerke can confirm the correct downpipe configuration.
• If you need an emissions-compliant option instead, see the Active Autowerke S63/N63 GESI catted downpipes.

Installation

• Active Autowerke does not publish an installation PDF for this downpipe. Confirm fitment with Speed Logic before ordering. Speed Logic offers professional installation — contact us to schedule an install.
• ATTENTION: Designed for off-road use only. The car will set a check engine light without an off-road flash tune — see Additional Parts Required above.
