Competition Link Downpipe
Fabspeed's Competition Link Downpipe is a catless downpipe for the F30/F32 335i and 435i, replacing the two restrictive factory catalytic converters with a free-flowing straight-pipe section for maximum power and sound. Expect greatly improved throttle response, noticeable power gains, and a more aggressive exhaust tone. It's a direct bolt-on install with no cutting or welding, though removing the cats can trigger a check engine light, so Fabspeed recommends pairing it with a tune or tuning device. There are two flange styles depending on your turbo's wastegate type, so check your build date (on the driver's door jamb sticker) before ordering.
Frequently asked
Which cars does the Competition Link Downpipe fit?
Fits your BMW 335i/435i (N55) (2011-2015). Fabspeed lists this piece for: BMW F30/F32 335i & 435i; BMW 335i & 435i (F30/F32). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Will removing the cats trigger a check engine light?
Removing the factory catalytic converters can trigger a check engine light, so Fabspeed recommends pairing this downpipe with a tune or tuning device.
How do I know which flange version I need?
It depends on your car's wastegate style: cars built before 08/2013 use a mechanical wastegate and a smaller flange, while cars from 08/2013 onward use an electronic wastegate and a larger flange. Your build date is on a sticker on the driver's side door jamb.
Is this legal for street use?
This is recommended for track and off-road use only; it's the purchaser's responsibility to verify legality in their region.
Which option should I choose?
The flange depends on your car's wastegate type, not personal preference: cars built before 08/2013 use a mechanical wastegate and the smaller flange, while cars from 08/2013 onward use an electronic wastegate and the larger flange. Check your build date on the driver's door jamb sticker, or contact Fabspeed if you're unsure which you have.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
