VRSF Catless Downpipes (N54 135i/335i)
VRSF Catless 3″ Downpipes for the BMW N54 engine, as found in the E8X 135i/1M and E9X 335i .
The catalytic converters in the downpipes on the N54 engines are a highly restrictive component. These free-flowing downpipes will free up horsepower, especially on tuned cars, while also allowing for faster turbo spool and a more aggressive exhaust note.
Gains from 25bhp.
