3" Race Downpipes

The VRSF 3" Race Downpipes are engineered to enhance the performance of the N54 engine found in the 2009-2016 BMW Z4 35i and 35is. Constructed from durable SS304 stainless steel, these 3-inch diameter downpipes replace the factory's restrictive catalytic converters, allowing for improved exhaust flow. This upgrade is designed to yield significant performance gains, with the manufacturer claiming an increase of 20-25 horsepower and 25-30 lb-ft of torque when paired with a tune. Installation of these downpipes is a complex process that typically requires working in a tight space. Some users have reported install times ranging from 3 to 4.5 hours, while others have indicated it took up to 12 hours due to the challenging nature of the job and the need to repeatedly adjust components like the v-bands. Professional installation is recommended for optimal results. It is important to note that this item will not fit RHD (Right-Hand Drive) cars without modification. Additionally, while VRSF offers a lifetime warranty against defects and fitment, it's crucial to confirm compatibility before purchase to avoid any fitment issues. Any concerns regarding fitment or product condition should be addressed with the seller immediately to ensure a smooth return or exchange process.
