Active Autowerke BMW B46 G2X 230i 330i 430i GESI Catted Downpipe

Active Autowerke BMW B46 Catted Downpipeu00a0

BMW introduced a new valve-tronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continuing into the G-chassis models. The Active Autowerke B46 downpipe for the 230i, 330i and 430 helps unleash some of the potential that is restricted by the OEM downpipe.

Turbochargers 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 B46 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke F-Chassis B46 Signature down pipe utilizes 3-1/2 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated a stainless flex joint and then to the ball flare to meet the OEM exhaust system.

This variant includes a 4" high flow GESI catalytic converter that will NOT produce a CEL!

The 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, perfect for use on 1996 and newer vehicles. 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.

The GESi UHO-Series Catalytic Converters are rated for engines putting out between 300 and 500 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!

Please 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.

NOTE: Federal law prohibits the tampering of an emissions control device. Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren't adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet the standards set by the EPA, not CARB.
