The ultimate catless downpipe offering maximum power and sound; recommended for track and off-road use
- Fits all BMW F30/F32 335i & 435i vehicles. We created two different flange styles to ensure proper fitment across all years
- Replaces the two restrictive factory catalytic converters with a free-flowing straight pipe section for maximum exhaust flow
- Greatly increased throttle response and noticeable power gains
- A more aggressive note to the exhaust tone
- Direct bolt-on replacement; no cutting or welding required
- Recommended for track and off-road use only (It is the purchaser's responsibility to verify legality and compliance in their region.)
- A check engine light is possible due to the deletion of factory catalytic converters. We highly recommend a tune or tuning device. Please contact us for all tuning information.
- There are two flange types for the 335i and 435i, depending on the wastegate style of the turbo. Pre 08/2013, a smaller flange is utilized. The build date of your car can be found on a sticker on the driver's side door jam. If you need assistance determining which version you have, please contact us before ordering.
