3.5-inch equal-length mid-pipe design for balanced exhaust pulses.

Electronic valve operation (valved axle-back or muffler section) for sound control (quiet vs aggressive) at the touch of a button.

Material options: high-quality T304 stainless steel or ultra-light Grade 5 titanium

Major weight savings vs factory exhaust: up to ~57.8 lb lighter with titanium; ~24.7 lb lighter with stainless steel.

Precision mandrel-bent tubing, TIG welds, and inclusion of cross-brace for structural rigidity.

High performance tone: crisper, more engaging sound with OEM downpipes; more aggressive tone when valves open or with optional free-flow downpipes.

Tips: premium exhaust tips with stylistic finishes (chrome, burnt, carbon, etc.) included.

OEM integration: maintains OEM valve control or offers included remote controller; designed to avoid check engine lights (CEL).

Fitment: Designed for 2020+ G80 M3, G82/G83 M4.

Modularity: mid-pipe and axle-back/rear section often installable independently.
