The Active Autowerke N55 downpipe for the M235i, 335i, 435i and M2 helps unleash some of the potential that is restricted by the OEM downpipe.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003eTurbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the N55 is quite restrictive, which results in slower exhaust gases and slower turbo spool.\u003cbr\u003eThe Active Autowerke F-Chassis N55 Signature down pipe utilizes 3.5 diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. This variant includes a 4.5\" high flow GESI catalytic converter that will NOT produce a CEL\u003c\/p\u003e \u003cp\u003e\u003cbr\u003eThe GESi G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi UHO-Series Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant. GESi proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most \"Check Engine Lights\". These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.\u003cbr\u003eThe GESi UHO-Series Catalytic Converters are rated for engines putting out between 500 and 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions.
