Downpipe Exhaust For N54 V2 2007-2010 BMW 335i / 2008-2012 BMW 135i | SPELAB
---tab Description---
Built for BMW N54 135i, 1M, 335i and 335is owners, this stainless downpipe helps reduce turbine-side restriction, sharpen turbo response, and support higher-flow performance setups.
What This BMW N54 Downpipe Does
The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.
By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.
BMW N54 Downpipe Key Features
- Adds 20-25 HP to the wheels & 25-30 TQ to the wheels.
- CAD/CAM designed cast bell mouth for seamless flange to pipe transition.
- Hand made from mandrel bent, tig welded 3″ 304 grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- Fits RHD and LHD models with no modification necessary.
- Gaskets & high quality grade 12 mounting hardware included.
- VRSF Lifetime Warranty against defects and fitment.
