Direct-fit Remus cat back for the BMW X3 F97 M Competition with S58B30A engine. Removes GPF for freer flow - mapping required to avoid check engine light.
Four 102mm angled carbon fibre tips + titanium internals for weight saving and visual impact
OEM valve control retained: factory button operation and drive mode integration work as intended
Fully stainless steel, shot-blasted finish, handmade in Austria
No adapters needed - engineered specifically for this chassis and engine combo
