While these cars have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the G80\/G82\/G87 which comprises this mid-pipe, a rear axle-back valved exhaust and a set of Active A-Flow catted downpipes. Together, this remake of the stock exhaust results in a G80\/G82\/G87 with an amazing sound. You will feel like you are driving a true M-car again.\u003c\/p\u003e\u003cp\u003eBMW introduced a new valvetronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continues into the G-Chassis models - the evolution to the S58 engine continues with the twin turbo variant used in the M-series vehicles. The Active Autowerke S58 downpipes for the G80 M3, G82 M4 and G87 M2 helps unleash some of the potential that is restricted by the OEM downpipes.\u003c\/p\u003e\u003cp\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 S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool. As the first step of the Active Autowerke G8X M3\/M4\/M2 collection, we are introducing our catted signature down pipe.\u003c\/p\u003e\u003cp\u003eThe Active Autowerke G80\/G82\/G87 S58 Signature down pipe utilizes 3 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated stainless flex joints and then down to 70mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 70mm.\u003c\/p\u003e\u003cp\u003eThis variant includes a pair of 4.5\" Active A-flow catalytic converters that will NOT produce a CEL guaranteed by Active Autowerke (full replacement within first two years of ownership).\u003c\/p\u003e\u003cp\u003eThe Active A-flow super high output catalytic converter features full 304 stainless steel construction, including the substrate. Active A-flow Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant. Active's proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most \"Check Engine Lights\" due to cat efficiency errors. These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.\u003c\/p\u003e\u003cp\u003eThe Active A-flow Catalytic Converters are rated for engines putting out up to 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.
