Active Autowerke Signature Race Only Catback Exhaust System for BMW G80 M3 & G82 M4

If you own a 2021 or newer BMW G80 M3 or G82 M4, it’s time to elevate your driving experience with the Active Autowerke Signature Race Only Catback Exhaust System. This exhaust upgrade is engineered specifically for those who crave the unmistakable sound and performance that only a race-inspired exhaust can deliver. With years of tuning experience dedicated to BMW M-cars, Active Autowerke has crafted a system that truly transforms your car’s auditory presence.

Unleash the Sound

Let’s face it: while the G80 and G82 are celebrated for their incredible performance, the factory exhaust can leave you feeling a bit underwhelmed in the sound department. The Signature Race Only exhaust system is designed to rectify that. With a fully open design and no OEM valves, you’ll experience a deep, aggressive tone that resonates with every throttle blip. For those looking to maximize their auditory experience, an optional exhaust DUMP right after the downpipes is available, ensuring that your M3 or M4 announces its presence at every turn.

Installation Made Easy

This exhaust system is a bolt-on upgrade, meaning you won’t need to make any cuts to your stock exhaust. Installation is straightforward and can be tackled by most DIY enthusiasts. Plus, if you ever want to revert to the stock setup, it’s as simple as unbolting the Active Autowerke system.

Performance and Construction

Constructed from 100% 304 brushed stainless steel, this exhaust system not only provides a race car growl but also ensures durability against rust and wear. The design maximizes exhaust flow while the included resonators help to mitigate unwanted rasp from the S58 engine, allowing you to enjoy that wide-open sound without compromise.
