Competition Link Downpipes
Cat-bypass downpipes for the Alfa Romeo Giulia Quadrifoglio (Type 952), removing the factory catalytic converters entirely with straight-through racing pipes for maximum flow and power across the rev range. CNC-machined billet stainless steel inlet flanges pair with CNC mandrel-bent tubing, and the pipes work with any rear cat-back exhaust, stock or aftermarket. Because the catalytic converters are removed, Fabspeed states these will trigger a check engine light and are strictly for closed track and off-road use, not for public roads. Fabspeed also notes these bypass pipes make less power than its own 200-cell HJS sport catalytic converters, so they're intended purely for all-out competition use alongside a tune that maximises power and disables the check engine light.
Frequently asked
Does the Competition Link Downpipes fit my Giulia Quadrifoglio?
This listing is specific to the Alfa Romeo Giulia Quadrifoglio. 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 this trigger a check engine light?
Yes, Fabspeed states removing the catalytic converters guarantees a check engine light, and these pipes are for closed track and off-road use only.
Do these make more power than Fabspeed's sport catalytic converters?
No - Fabspeed notes these cat-bypass pipes actually make less power than its own 200-cell HJS sport catalytic converters, so they're purely a competition option.
Will this work with my existing rear exhaust?
Yes, it works with any rear cat-back exhaust, stock or aftermarket.
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.
