Unlock more power and sharper throttle response from your BMW X3 or X4 with our GCA Performance B48 Downpipe, engineered specifically for 2018+ G01 and G02 models.
Designed by German Car Accessories under our GCA Performance line, this high-flow downpipe replaces the restrictive factory unit to improve exhaust flow, reduce backpressure, and maximize turbocharger efficiency. The result is quicker turbo spool, improved engine response, and a deeper, more aggressive exhaust note.
Manufactured from premium T304 stainless steel with precision TIG welds, this downpipe is built to withstand extreme temperatures while delivering exceptional durability and OEM-quality fitment. It's the ideal upgrade for stock or tuned B48-powered BMW X3 and X4 models.
