Unlock the full performance potential of your BMW with the German Car Accessories 2012-2013 BMW M135i / M135i xDrive PWG Downpipe. Developed under the GCA Performance lineup, this high-flow downpipe is engineered specifically for early-production F20 and F21 BMW M135i and M135i xDrive models equipped with the 3.0L Turbocharged N55 Inline-6 engine featuring the Pneumatic Wastegate (PWG).
Replacing the restrictive factory downpipe significantly improves exhaust flow, reduces back pressure, and allows the turbocharger to spool more efficiently. The result is increased horsepower and torque potential, faster turbo response, sharper throttle response, and a deeper, more aggressive exhaust note that unleashes the true character of the N55 engine.
Constructed from high-quality T304 stainless steel, this performance downpipe is designed to withstand extreme exhaust temperatures while providing excellent corrosion resistance and long-lasting durability. Precision TIG welding ensures superior strength, leak-free performance, and OEM-quality fitment for straightforward installation.
Whether paired with ECU tuning or additional GCA Performance upgrades, this downpipe provides an excellent foundation for extracting maximum performance from your BMW M135i.
German Car Accessories proudly stands behind every GCA Performance product, and this downpipe is backed by a 1-Year Warranty.
