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.\u003cbr\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\u003e\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! \u003cbr\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 certified 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\u003e\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. Say goodbye to Check Engine Lights and failed emissions tests!\u003cbr\u003e\u003cbr\u003ePlease Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eNO CEL when using this downpipe\u003c\/li\u003e\n\u003cli\u003eDesigned to be as unrestrictive as possible\u003c\/li\u003e\n\u003cli\u003eGESI EPA registered high flow and fully OBD2 compliant\u003c\/li\u003e\n\u003cli\u003eHigh flow 4.50\" GESI cat with 3.50\" piping allows for maximum power output\u003c\/li\u003e\n\u003cli\u003eQuicker turbo spool - improved power over stock\u003c\/li\u003e\n\u003cli\u003eRated for 500 to 850 hp applications\u003c\/li\u003e\n\u003cli\u003eWithstands up to 1500° F\u003c\/li\u003e\n\u003cli\u003eCan reach operational efficiency within 9 seconds of startup\u003c\/li\u003e\n\u003cli\u003eEasily bolts-on – no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eDurable construction from TIG welded 304 stainless steel\u003c\/li\u003e\n\u003cli\u003ePrecise fitment\u003c\/li\u003e\n\u003cli\u003eModular design for later upgrades\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003cli\u003eUltra high flow 400 cell per square inch catalyst\u003c\/li\u003e\n\u003cli\u003eEPA certified for use on OBD2 vehicles (1996 and newer) except in California\u003c\/li\u003e\n\u003cli\u003eFull 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003e304 stainless steel substrate in the catalytic converter is furnace braised to the mantle for outstanding durability\u003c\/li\u003e\n\u003cli\u003eGESi® proprietary precious metal loading technology ensures greatly reduced emissions\u003c\/li\u003e\n\u003cli\u003eIdeal for Forced Induction Applications with no loss of HP\u003c\/li\u003e\n\u003cli\u003eBoth passengers and drivers are safe from harmful emissions and noise\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignature Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000000\"\u003e\u003cspan face=\"Liberation Serif, serif\"\u003e\u003cspan size=\"3\"\u003eThe speed of a turbo’s impeller wheel is limited by exhaust back pressure.
