Overview

The CarBahn Titanium Exhaust System is a complete cat-back exhaust designed for the BMW M3 and M4 G80/G82/G83 models. It is constructed from titanium for maximum durability and light weight, reducing the vehicle's weight by 25-40 lbs. The system retains the OEM catalyst and electronic controller valve to provide a mellow sound during normal driving and increase flow for maximum power when the valve opens during wide-open throttle. It also includes titanium and carbon exhaust tips.

Show original supplier description

The CarBahn Titanium Exhaust System is a high-flow, complete cat-back exhaust meticulously engineered for the BMW M3 and M4 G80/G82/G83 models. Constructed from premium titanium, this system offers exceptional durability while significantly reducing weight, with gains typically ranging from 25 to 40 pounds depending on the specific application. This ensures a more responsive and agile driving experience. This intelligent design allows for a refined, mellow exhaust note during everyday driving, effectively eliminating the drone often found in aftermarket systems. However, when the vehicle's ECU opens the valve at wide-open throttle, the exhaust flow dramatically increases, unleashing a sporty and aggressive sound profile without being excessively loud. This comprehensive exhaust system comes complete with striking titanium and carbon exhaust tips, adding a visual flourish to complement its performance enhancements. This exhaust is compatible with various BMW M3 and M4 G80/G82/G83 models from 2021 onwards, including RWD and xDrive variants of the M3 Competition, M3, M4, and M4 Competition.
