Exhaust system Capristo BMW 435i F32/F33/F36

02BM02103001

Exhaust system for the BMW 435i in the F32 Coupe, F33 Convertible and F36 Gran Coupe bodies. The N55 straight six is the engine the 4 Series was built around, and the standard exhaust gives away almost nothing of the six-cylinder character it has.

How it works

The valves stay closed at light load, so cruising noise is close to standard. Opened, the gas path shortens and bypasses the damping chambers, which is where the volume and the sharper response come from. Capristo makes its own valves and the reinforced design is patented to keep resonance out of the cabin.

Material and build

T309 (1.4828) stainless steel, rated for continuous temperatures above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany, developed on 3D laser scans of the original pipework.
