Experience ultimate performance with BIMMERSPEED N63/S63 Racing Downpipes! Featuring a high quality 89 mm stainless steel Catless design, these downpipes can deliver an additional 20hp and 33tq gains with proper tuning. TIG-welded and CNC machined flanges for strength and durability, boasting improved spool, increased power, and a much more aggressive exhaust note, these downpipes dramatically reduce back pressure and eliminate the restrictive catalytic converters.
