GT450 Race Performance Package for the Porsche 981 Cayman GT4 and Boxster Spyder (2015-2016), Fabspeed's complete power solution bundling the Valvetronic Exhaust System, Race Headers, an IPD Competition Plenum, BMC F1 Replacement Air Filters and Fabspeed's XperTune tuner with the GT450 map. On Fabspeed's dyno the package pushed output past 400whp, adding 53whp at 6400rpm and over 65 lb-ft of torque at 3600rpm across the rev range. Because the Race Headers remove the OEM catalytic converters, this package is intended for closed-course track and off-road use only, not public roads. All parts bolt on with no cutting or welding, and the XperTune documentation for uploading the GT450 flash is included at purchase. Choose from carbon fiber or single-wall stainless tips, with an optional Porsche slip-on turndown.

Frequently asked

Does the GT450 Race Performance Package fit my Cayman GT4?

This listing is specific to the Porsche Cayman GT4 (981). 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.

Is this street legal?

No. The Race Headers in this package remove the OEM catalytic converters, so Fabspeed states the package is strictly for closed-course track and off-road use, and will trigger a check engine light on OBD2 cars.

Does this include the ECU tune?

Yes, the package includes Fabspeed's XperTune with the GT450-specific map, and documentation for uploading the flash is sent with your purchase.

How much power does the full package add?

53whp at 6400rpm and over 65 lb-ft of torque at 3600rpm, pushing output past 400whp on Fabspeed's dyno.

Does Fabspeed tune out the check engine light?

No, Fabspeed explicitly states they do not tune out check engine lights.

Which option should I choose?

Tip finish (carbon fiber or single-wall stainless in various finishes) is a cosmetic choice. Add the Porsche slip-on turndown tips if you want a track-style rear look.

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.
