Frequently asked
Does the Sport Headers Without Heat fit my 911 Carrera?
This listing is specific to the Porsche 911 Carrera (993). 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 I lose cabin heat with these headers?
Yes. These headers don't have heat exchanger boxes, which Fabspeed says makes them best for track use or areas with warmer climates since you lose the hot air to the cabin.
Do they affect emissions?
No, Fabspeed says emissions aren't affected because the OEM catalytic converters stay in place, unaffected, downstream of these headers.
How do I know which flange style I need?
Fabspeed splits it by build date: 1994 to mid-1995 cars use the Bischoff flange, triangular with a flat bottom and 3 bolts, while 1996 to 1997/98 cars use the Gillet flange, which is round with 3 bolts.
Which option should I choose?
These headers are a direct replacement for both factory flange types, but you must pick the right one: Bischoff is the earlier triangular flat-bottom 3-bolt flange (1994-1996.5), Gillet is the later round 3-bolt flange (1996-1998). If you're not sure which your car has, contact us before ordering and we'll confirm it with you.
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.
