Transform the sound and performance of your BMW with the Horizon Motorsport V1 Catback Exhaust, engineered for S58-powered G80 M3 and G82/G83 M4 models. This item is currently made to order, but a new stocking shipment will be arriving soon.

Crafted from premium 304 stainless steel, the V1 system delivers exceptional durability and refined craftsmanship. Designed using precise CAD modeling for a direct bolt-on fit, it installs easily with no cutting or welding required, utilizing factory mounting points for seamless integration.

The 3.5-inch midpipe is optimized for improved exhaust flow, delivering enhanced throttle response and performance potential while deepening the overall tone. A wireless valve controller with two remotes gives you the ability to open or close the valves on demand—ideal for those in HOA-regulated areas or anyone who wants the flexibility to quiet their car when needed, without losing the exhilarating sound of the S58 engine during spirited driving.

Every V1 system is meticulously TIG-welded and built to withstand harsh conditions, ensuring lasting performance and corrosion resistance. Acoustic tuning within the muffler and resonator design provides a refined tone at low RPMs and a raw, motorsport-inspired character under load.

An upgraded exhaust brace is included for additional clearance and improved fitment, while high-strength clamps and hardware simplify installation and ensure long-term reliability. Horizon Motorsport backs this system with a limited warranty covering manufacturing defects for your peace of mind.

Choose from three premium exhaust tip finishes—Polished, Brushed, or Matte Black—to complete your build.
