DDS Performance is proud to release the advanced DDS Performance Signature Catted Downpipes with GESI G-Sport cats for the BMW G80 M3 and G82 M4. While these cars have received rave reviews for their performance, the sound is muffled, leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, DDS Performance has created a full exhaust system for the G80 and G82 which comprises this mid-pipe, a rear axle-back valved exhaust, and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a G80 and G82 with a fantastic 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 DDS Performance S58 downpipes for the G80 M3 and G82 M4 help unleash some of the potentials that are 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 downpipe in the S58 is a bit restrictive, which results in slower exhaust gases and a slower turbo spool. We are introducing our catted signature downpipe as the first step of the DDS Performance G80 M3/M4 collection.

The DDS Performance G80/G82 S58 Signature downpipe utilizes 3-inch diameter stainless steel piping in order to provide more power, a quicker spool, and extreme durability. We've incorporated stainless flex joints, then up to 70mm, to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 70mm.
