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 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. BMW 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. 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 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. The 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 exhaust diameter of 70mm. Features: Casted upper stainless steel head for precise fitment  3" diameter piping allows for maximum power output  Quicker turbo spool Easily bolts-on - no cutting or welding required  Durable construction from TIG welded 304 stainless steel Precise fitment Ideal for Forced Induction Applications with no loss of HP Made in Miami, Florida Active Autowerke G8X S58 Signature Downpipes Benefits The speed of a turbo's impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipes, your S58 can rev quicker, and deliver more horsepower and torque. Minimizing back pressure while retaining daily drive-ability was the goal of our S58 downpipes. Owners can now upgrade to a product that is affordable, reliable, and easy to install. After months of research and development, our engineers settled on a 3 inch diameter pipe which utilizes the least number of bends possible. The large volume helps the turbo spool as quickly as possible by eliminating back pressure during spool up. Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your S58! NOTE: FITS S58 VEHICLE G80 M3, G82 M4 and G87 M2
