Remus Valved Cat-Back/Catback Exhaust System Non-Resonated Quad 102mm Tips for BMW M3 F80 2015+ (3 Series Saloon/Sedan) Stainless Steel Performance ECE Approved Plug & Play Valve Control

Remus performance exhaust upgrade for F80 M3 (2015 onwards) with valve control and quad 102 mm tips

Unlock a fierce motorsport soundtrack and sharper response with this premium rear section system from Remus. Designed for the F80 M3 saloon, it replaces everything from the catalyst back and integrates seamlessly with the factory valve electronics for on-demand volume and tone. Expect a deeper idle, hard-edged acceleration note and head-turning presence, all while retaining everyday refinement when the valves are closed.

Built in Austria by craftsmen using full stainless construction and a shot-blasted finish, this valved exhaust is engineered for reduced backpressure, improved flow and weight savings. The result is a high quality upgrade that looks as good as it sounds, with perfect alignment and no cutting required.
