VRSF 3″ High Flow Downpipes
For your BMW 135i, 1M, 335i & 335IS (2007-2010) with the N54 engine
VRSF 3" High Flow Downpipes for the N54 engine of the BMW 135i and 335i. These downpipes offer the best value for money and provide significant performance improvements, with gains of up to 30 hp and 35 Nm of torque when combined with a modified DME mapping. By replacing the restrictive catalysts of the original N54 downpipes, back pressure is drastically reduced, resulting in faster turbo response, more power and a more aggressive exhaust note.
Unlike many competitors who reduce the diameter of their downpipes as they reach the turbos, VRSF 3" N54 downpipes feature a full 3" diameter all the way to the 2.5" flange, allowing for improved flow. These downpipes are handcrafted from 304 stainless steel and come with a lifetime warranty and our "No Hassle" satisfaction guarantee for fit and manufacturing defects. Each kit includes heavy duty grade 12 quality nuts, bolts and washers, as well as two midpipe gaskets. VRSF also offers additional installation accessories, such as the turbo to downpipe clamp and gasket, which are sold separately. While not required for installation, they are highly recommended if the original accessories have more than 50,000 miles on them.
