1st Competition Link Downpipes
Fabspeed's 1st Competition Link Downpipes eliminate the heavy, restrictive factory catalytic converters on the F80/F82/F83 M3 and M4 with straight-pipe, high-flow stainless steel downpipes, built for maximum power and an exhilarating sound. Bent over an internal mandrel so the tube keeps a constant diameter through the bend, unlike crush-bending. with minimal welds to reduce failure points and maximize flow, they're designed to fit seamlessly with the factory exhaust, Fabspeed's Valvetronic Exhaust System, or any other aftermarket system built to OEM fitment. Because they remove the factory cats they may trigger a check engine light, and Fabspeed markets them strictly for off-road competition and race use.

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 this fit with an aftermarket exhaust I already have?
Yes, it's designed to fit seamlessly with the factory exhaust, Fabspeed's Valvetronic Exhaust System, or any other aftermarket system built to OEM fitment.
Will removing the cats trigger a check engine light?
It may, since it replaces the factory catalytic converters; Fabspeed markets these strictly for off-road competition and race use.
Why mandrel-bent with minimal welds?
Fewer welds mean fewer potential failure points under regular use, and mandrel bending keeps flow at its best through the bends.
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?
