Description
Unlock the full potential of your 2012–2013 BMW 335i or M135i with the Palenon Performance PWG N55 Downpipe, designed exclusively for enthusiasts seeking improved performance, enhanced throttle response, and a richer exhaust note. This premium high-flow catted downpipe is engineered to deliver maximum exhaust flow while maintaining emissions compliance, making it the perfect upgrade for street-driven vehicles tuned beyond Stage 1.
Crafted from TIG-welded T304 stainless steel, this downpipe offers exceptional strength, corrosion resistance, and durability to withstand the rigors of high-performance driving. The optimized flow design features smooth mandrel bends and an enlarged 4-inch diameter inlet, significantly reducing backpressure and promoting faster turbo spool for a noticeable increase in horsepower and torque.
Precision is paramount, and the CNC-machined stainless steel flanges provide an exact OEM-quality fit, ensuring leak-free installation and long-term reliability. Equipped with two O2 sensor bungs positioned for easy OEM sensor reinstallation, this downpipe seamlessly integrates with your vehicle’s factory emissions system without triggering check engine lights.
With a proper Stage 2+ tune, expect power gains in the range of 20 to 25 horsepower, coupled with a sharper throttle response and an aggressive, sportier exhaust tone—especially prominent under wide-open throttle and during cold starts.
