- TIG-welded 304 stainless steel construction for race inspired performance and durability.
- Engineered for maximum flow with minimal turbulence points for increased performance and improved throttle response.
If you are looking for increased exhaust velocity and improved performance and throttle response, you need a header/down pipe for your BMW. The aFe Power down pipe eliminates the catalytic converter for maximum exhaust flow for popular BMW applications. These headers/down pipes are 100% TIG-welded by certified craftsmen for race proven strength and durability. TIG-welding provides the strongest welds reducing stress cracks. A unique tapered design and mitered collectors are used to increase exhaust velocity and increase useable torque. This means more aggressive throttle response and increased passing power. The headers/down pipes use factory mounting locations for the O2 sensors. All hardware and brackets are included for a hassle-free installation.
CNC Machined Flanges CNC machined flanges are used to ensure a leak free seal and hassle-free installation.
100% TIG-Welded Welded by certified craftsmen for race proven strength and durability, TIG-welding provides the strongest welds reducing stress cracks.
Mitered Merge Collectors Mitered merge collectors are used for optimal scavenging, reducing exhaust turbulence and maximizing performance.
